Problem 4 Pg230
In two separate studies, the actual difference between the means of a treated group
and an untreated group is 3 points. However, in on study, the 𝜎 𝑚1 − 𝑚2 is very
large and so 3 points is not found to be significant. In the other study 𝜎 m1 − m2 is
very small and so the 3 points is found to be significant. What might have caused
this big difference in the 𝜎 𝑚1 − 𝑚2 for the two studies?
Problem 8 Pg231
In a study of the effect of a new drug on the alleviation of asthma symptoms, the σm
for the symptom relief in the patient group that received the new drug is 1.45, and
the σm for symptom relief in the group that did not receive the new drug 1.22.
Calculate the σ m1-m2

Colorado State University Competitive Environment & Descriptive Statistics Paper
Business ProfitsThe research firm LL Research collected data from 200 client businesses. They want to determine how the businesses compare among four variables:2015 Profit in millions of dollars2016 Profit in millions of dollars2015-2016 Two-Year Change in Daily Average Customer VisitsTwo-Year Average Number of EmployeesData collected for the sample of 200 businesses is contained in the file named Businesses. Be sure to use all 200 data points.Managerial ReportPrepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how each of the variables contributes to the success of a client's business. Be sure to include the following three items in your report.Compute descriptive sample statistics (mean, median, two quartiles Q1 and Q3 (using QUARTILE.EXC), minimum, maximum, range, interquartile range, sample standard deviation, and coefficient of variation) for each of the four variables along with an explanation of what the descriptive statistics tell us about the client businesses.In this case, which measure of central tendency would be best for this application? Explain why.Which measure of variation would be best for this application? Explain why.How can one use the above descriptive statistics to understand the businesses better?Which graphical displays of data would you use to help understand or complement the above descriptive statistics? Explain how and why.Note: QUARTILE.EXC works only for Excel 2010 or newer.Compute the percent change in profit from 2015 to 2016 for each business.What would the percent change tell us in this application?Then use the z-score to determine which businesses were outliers with respect to percent change in profit.How would identifying outliers be useful in this application?What advice might you give to businesses that are outliers?How else would you determine outliers?Compute the sample correlation coefficient, showing the relationship between percent change in profit and each of the other two variables (2015-2016 Two-Year Change in Daily Average Customer Visits and Two-Year Average Number of Employees).Explain what the correlation coefficients tell us about the three pairs of relationships. Use tables, charts, or graphs to support your conclusions. Write a report that adheres to the formatting and APA expectations outlined in the CSU Global Writing Center (Links to an external site.). As with all written assignments at CSU Global, you should have in-text citations and a reference page. Submit your Excel file in addition to your report.Requirements:The paper must be written in third person.Your paper should be four to five pages in length (counting the title page and references page) and cite and integrate at least one credible outside source. The CSU Global Library (Links to an external site.) is a great place to find resources.Include a title page, introduction, body, conclusion, and a reference page.The introduction should describe or summarize the topic or problem. It might discuss the importance of the topic or how it affects you or society as a whole, or it might discuss or describe the unique terminology associated with the topic.The body of your paper should answer the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure the Word document is in paragraph format, not numbered answers like a homework assignment.The conclusion should summarize your thoughts about what you have determined from the data and your analysis, often with a broader personal or societal perspective in mind. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs. Your conclusion should emanate (be aligned with) your findings.Include any tables of data or calculations, calculated values, and/or graphs associated with this problem in the body of your assignment.Document formatting, citations, and style should conform to the CSU Global Writing Center (Links to an external site.). A short summary containing guidelines for paper formatting, citations, and references is contained in the New Sample APA Paper (Links to an external site.). In addition, information in the CSU Global Library (Links to an external site.) has many helpful areas (Writing Center, Writing Tips, Template Examples/Papers Essays, and others).
