Critical Thinking – Probability, statistics homework help – MATHEMATICS

Sky Hospital ConsortiumThe Sky Hospital Consortium consists of 40 hospitals in various parts
of the US. After being discharged, patients are given a survey to
determine if they are satisfied with the overall service. In most cases
patients are satisfied. However, some are dissatisfied. In addition, out
of those who responded as being dissatisfied, some filed a formal
complaint. In the Excel file, Hospitals, linked at the
bottom of the page, are the results for the patients during a specific
year. The Sky Hospital Consortium is divided into the West, Central, and
East Regions. The Sky Hospital Consortium wants to evaluate the performance of the
hospitals. The Consortium wants to know which hospitals have the fewest
complaints. You are to assist in the data analysis by using your
knowledge of probability and conditional probability to help with the
ranking of the hospitals, as well as each Region.Managerial Report
Prepare a report (see below) with your ranking of the hospitals based
on the probabilities and conditional probabilities, as well as the
analysis of each region. Include the following seven (7) items in table
format to support your ranking. Be sure to use five (5) decimal places for your probabilities in the table, as some of them might be quite small.The probability of a patient responding “Dissatisfied” in each of the three different regions.
The probability of a patient filing a formal complaint in each of the three different regions.
The probability of a patient filing a formal complaint given a
patient response of “Dissatisfied” in each of the three different
regions.
The probability of a patient responding “Dissatisfied” for each hospital.
The probability of a patient filing a formal complaint for each hospital.
The probability of a patient filing a formal complaint given a patient response of “Dissatisfied” for each hospital.
Rank the hospitals within each region for each of
the probabilities in 4 – 6. In other words, only rank the hospitals in
the West region against the other hospitals in the West region. Perform
the same analysis for the other two regions. Then, within
each region, find the sum of the ranks and get an overall ranking for
each hospital. Evaluate and discuss the meaning of your results. Use
tables, charts, graphs, or visual dashboards to support your findings.
Write a report that adheres to the Written Assignment
Requirements under the heading “Expectations for CSU-Global Written
Assignments” found in the CSU-Global Guide to Writing and APA Requirements.
As with all written assignments at CSU-Global, you should have in-text
citations and a reference page. An example paper is provided in the MTH410 Guide to Writing with Statistics, linked at the bottom of the page.Your report must contain the following:A title page in APA style.
An introduction that summarizes the problem.
The body of the paper should answer the questions posed in the
problem by communicating the results of your analysis. Include results
of calculations, as well as charts and graphs, where appropriate.
A conclusion paragraph that addresses your findings and what you have determined from the data and your analysis.
Submit your Excel file in addition to your report.West

Introduction
The purpose of this paper is to provide some general guidance in the writing of papers
using statistics and associated tests. The paper provides some general tips for writing and the use
of statistics. An example prompt is included, followed by a sample paper.
General Tips for Writing a Math Paper:





Organization:
o Turn your prompt into headings for paper sections. This will help you to make
sure you include all of the required information and analysis. It also helps the
reader identify the material.
o Your paper needs:
 A separate title page using APA style requirements (running header, page
numbers, course, instructor, your name, date, etc.).
 An introduction (often a summary or abstract of the problem).
 A body of the paper that answers the questions posed in the problem and
includes calculations and graphs associated with this problem. This is
where you can turn your prompt into headings. All references need to be
properly cited.
 A conclusion paragraph that addresses your findings and what you have
determined from the data and your analysis.
 A separate sheet for references.
o There are templates that use APA style that you can insert your material into. If
you really struggle with formatting, this may be an option for your first paper or
two. If you use a template, remember to double-check it to remove any extra
instructions or pages or other elements that weren’t used.
In general, numbers less than 10 are to be written in word form. However, if you have
numbers in this range that carry decimals, write them in numeral form.
Never use or interpret a statistic or test that you don’t fully understand.
Target your audience and present as much information as necessary to allow the reader to
make an independent interpretation.
Make use of graphs and tables to display information in an easily understood manner.
Format them the same throughout, and make sure you don’t manipulate axes.
If you are referring to a statistic that is less commonly used, explain how you calculated
it. (It is not necessary to explain mean, but it may be necessary to explain how you set up
an ANOVA test.)
Be clear about your sample and its corresponding population.
Be direct in writing descriptive statistics (The mean in Group A is 22.9 units.).

Translate the meaning of the statistic for the reader. Write plainly and then back it up
with statistical evidence. For example: Men and women scored equally well on this study
(t = 0.25, p < 0.01).

Heavenly Chocolates manufactures and sells quality chocolates at its plant and retail store in Bozeman, MT. Three years ago, the company developed a website and began sales on the internet. Website sales have exceeded expectations and management is now considering strategies to continue to increase its sales. To learn more about its sales, Heavenly Chocolates selected a sample of 50 random transactions from its previous month’s sales. The transaction data shows the day of the week the purchase was made, the type of browser used in the transaction, the time spent on the website, the number of website pages viewed, and the amount spent by the customer. The data is shown in a file named Chocolate. Heavenly Chocolates would like to determine if time spent on the website or the number of pages viewed influence the total purchase. They would also like to examine any effect that day of the week and browser type have on sales. Managerial Report Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how the variables contribute to the sales of chocolate. Be sure to include the following four (4) items in your report. 1. Descriptive statistics (mean, median, range, and standard deviation) for each of the three variables along with an explanation of what the descriptive statistics tell us about the sales. 2. A breakdown using descriptive statistics examining the effect of days of the week on sales. Evaluate the results. 3. A breakdown using descriptive statistics examining the effect of browser type on sales. Evaluate the results. 4. Descriptive statistics (correlation coefficient) showing the relationship between sales (in dollars), and each of the other two variables. Evaluate the relationships between sales (in dollars) and each of the other variables (time spent and pages visited). Use tables, charts, graphs, or visual dashboards to support your conclusions. Make recommendations for continuing to develop sales to the management. Write a report that adheres to the Written Assignment Requirements under the heading “Expectations for CSU-Global Written Assignments” found in the CSU-Global Guide to Writing and APA Requirements. As with all written assignments at CSU-Global, you should have in-text citations and a reference page. Your report must contain the following:   A title page An introduction GUIDE TO WRITING WITH STATISTICS   4 A body of the paper that answers the questions posed in the problem and calculations and graphs associated with this problem. A conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. Submit your Excel file in addition to your report. Note: Prompt adapted from the “Heavenly Chocolate Website Transactions Case Problem 4,” D. Anderson, D. Sweeney, T. Williams, J. Camm, & J. Cochran, 2015, Essentials of statistics for business and economics. (7th ed.), p. 167,168. The following pages contain the sample paper corresponding to the prompt written above. Read through it for ideas on how to write your own papers. HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) Heavenly Chocolates Web Sales Analysis Student Name MTH410 – Quantitative Business Analysis Colorado State University–Global Campus Instructor Name Date 1 HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) 2 Heavenly Chocolates Web Sales Analysis Website transactions are an important segment of sales and distribution today. Any business developing a market for online sales would be wise to analyze data from both the general marketplace and its own specific customer segment. Analysis of this data can provide insight into further development of sales. Heavenly Chocolates data-mined their transactions for the previous month to gather a random sample of 50 customer transactions. The sample recorded the day of the week the purchase was made, the type of browser used in the transaction, the time spent on their website, the number of website pages viewed, and the amount spent by the customer. The purpose of this analysis is to determine if the time spent on the website or the number of pages viewed influences the total purchase. The impact of day of the week and browser type on sales will also be studied. Overview of Online Sales The 50 customers sampled spent a total of $3,406.41 in the previous month. This is an average of $68.10 per customer. The purchases ranged from a $17.80 to $158.50. The average customer spent 12.8 minutes on the website. Time spent on the website ranged from 4.3 minutes to 32.9 minutes. The typical customer viewed almost five pages, with two as the minimum and ten as the maximum. The data set is summarized below in Table 1. Table 1 Summary of Online Sales Sample Time (min) Pages Viewed Amount Spent ($) mean 12.8 4.8 68.1 median 11.4 4.5 62.2 std dev 6.1 2 32.3 min 4.3 2 17.8 HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) 3 Table 1 Summary of Online Sales Sample (Continued) Time (min) Pages Viewed Amount Spent ($) max 32.9 10 158.5 range 28.6 8 140.7 SUM ($) 3406.41 Note: Data compiled from the “Heavenly Chocolate Website Transactions Case Problem 4,” D. Anderson, D. Sweeney, T. Williams, J. Camm, & J. Cochran, 2015, Essentials of statistics for business and economics. (7th ed.), p. 167,168. Impact of Day of the Week on Sales The daily sales breakdown reveals some interesting patterns. Sunday is the lowest sales day, from the perspective of both total sales ($218.15) and average sales ($43.60). Monday and Friday were the best days in terms of overall sales performance. Monday had the highest mean (average) sales at $90.40, while Friday had the highest total sales at $945.43 for roughly 28\% of the sample total. See Table 2 for a complete breakdown of the impact of the day of the week on amount spent, time spent on the website, and number of pages viewed.

Anderson, D. Sweeney, T. Williams, J. Camm, & J. Cochran, 2015, Essentials of statistics for business and economics. (7th ed.), p. 167,168. By almost every measure, Monday is the best day for sales. Friday follows closely (see Table 2). It makes logical sense to recommend that the marketing department develop advertising targeted for Monday and Friday. Weekends are subpar and midweek statistics are nearly equivalent. Targeting sales or special packages for midweek may produce some increased traffic. If these recommendations are implemented, follow-up analysis is recommended to see if the desired results are being produced. HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) 5 Impact of Browser on Sales There were also sales differences revealed by breaking the data down by browser type. Customers using Internet Explorer to complete their transactions accounted for the highest total sales at $1,656.81; however, this value was achieved on volume (see Table 3). Internet Explorer had the lowest average sale at $61.36 while Firefox customers averaged $76.80 per transaction. Table 3 Breakdown of Sales by Browser Firefox Internet Explorer Other Total mean 76.8 61.36 74.5 68.1 median 68 55.6 67.4 62.2 std dev 38.9 29.2 24.6 32.3 min 27.9 17.8 52.2 17.8 max 158.5 126.4 120.3 158.5 range 130.6 108.6 68.1 140.7 count 16 27 7 50 SUM ($) 1,228.21 1,656.81 521.39 3,406.41 Note: Data compiled from the “Heavenly Chocolate Website Transactions Case Problem 4,” D. Anderson, D. Sweeney, T. Williams, J. Camm, & J. Cochran, 2015, Essentials of statistics for business and economics. (7th ed.), p. 167,168. The opportunity here is to target premium packages for advertising specific to Firefox. Value packages could be created for advertising specific to Internet Explorer. This promotion should be combined with the recommendations given regarding days of the week and subjected to a follow-up analysis to check for results. Relationship between Amount Spent and Website Use The other feature of this analysis is to evaluate the relationship between amount spent by customers and how much time they spent on the website with the additional variable of number HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) 6 of pages viewed also taken into account. For this, a correlation analysis was performed. The correlation coefficient between time spent on the website and amount spent in dollars was moderately positive (r = 0.58). A similar moderately positive correlation coefficient (r = 0.60) was found between the variables of time spent on the website and number of pages visited. The strongest correlation was found between number of pages viewed on the website and amount spent. This correlation coefficient (r = 0.72) approaches a strong positive correlation (see Figure 1). This suggests that there may be some merit in trying to guide customers to view more pages. 180.00 160.00 Dollars Spent 140.00 120.00 100.00 80.00 60.00 40.00 20.00 0.00 0 2 4 6 8 10 12 Pages Viewed Figure 1. Relationship Between Pages Viewed and Dollars Spent. Data compiled from the “Heavenly Chocolate Website Transactions Case Problem 4,” D. Anderson, D. Sweeney, T. Williams, J. Camm, & J. Cochran, 2015, Essentials of statistics for business and economics. (7th ed.), p. 167,168. A common tactic is to guide customers to pages that have also been viewed by other customers viewing the product on the current page. Another suggestion is to pair pages and suggest that customers who purchased the product on the current page also frequently purchased a product on the linked page. As with previous suggestions, follow-up analysis should be performed to check results. On a cautionary note, this can be overdone. The statement from HEAVENLY CHOCOLATES WEB SALES ANALYSIS (Sample) 7 Essentials of Statistics for Business and Economics that correlation is a measure of linear association and not causation should also be duly noted (Anderson, et al., 2015). Conclusion The analysis of this sample of 50 random customer transactions revealed several items to be used in the development of continued growth at Heavenly Chocolate. There is positive correlation between all three variables, but the strongest correlation is between number of pages viewed and amount of sales. There is adequate reason to pursue linking pages and making suggestions for customer purchasing. Monday and Friday are the best sales days. Firefox customers spend the most, but Internet Explorer customers provide the highest volume. Packaging and marketing strategies can be developed using this information. This analysis validates the use of statistical tools to provide insight into new strategies. Follow-up analysis is also mandated to find out if the strategies are producing results.
