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).

QNT275 DeVry University Calculating Binomial Probabilities
Statistical Concepts: ProbabilityBinomial Probability Distribution Calculating Binomial Probabilities NOTE:For question 1, you will be using the same data file your instructor gave you for the Week 2 Lab. Using the data file from your instructor (same one you used for the Week 2 Lab), calculate descriptive statistics for the variable (Coin) where each of the thirty-five students in the sample flipped a coin 10 times. Round your answers to three decimal places and type the mean and the standard deviation in the grey area below.Create scatter plots for the binomial distribution when p=0.50, p=0.25, and p=0.75 (see directions above).Paste the three scatter plots in the grey area below. List the probability value for each possibility in the binomial experiment calculated at the beginning of this lab, which was calculated with the probability of a success being ½. (Complete sentences not necessary; round your answers to three decimal places.) Give the probability for the following based on the calculations in question 3 above, with the probability of a success being ½. (Complete sentences not necessary; round your answers to three decimal places.) Calculate (by hand) the mean and standard deviation for the binomial distribution with the probability of a success being ½ and n = 10. Either show your work or explain how your answer was calculated. Use these formulas to do the hand calculations: Mean = np, Standard Deviation = Calculate (by hand) the mean and standard deviation for the binomial distribution with the probability of a success being ¼ and n = 10. Write a comparison of these statistics to those from question 5 in a short paragraph of several complete sentences. Use these formulas to do the hand calculations: Mean = np, Standard Deviation = Calculate (by hand) the mean and standard deviation for the binomial distribution with the probability of a success being ¾ and n = 10. Write a comparison of these statistics to those from question 6 in a short paragraph of several complete sentences. Use these formulas to do the hand calculations: Mean = np, Standard Deviation = Using all four of the properties of a Binomial experiment (see page 201 in the textbook) explain in a short paragraph of several complete sentences why the Coin variable from the class survey represents a binomial distribution from a binomial experiment.Compare the mean and standard deviation for the Coin variable (question 1) with those of the mean and standard deviation for the binomial distribution that was calculated by hand in question 5. Explain how they are related in a short paragraph of several complete sentences. Mean: Standard deviation: NOTE:for questions 2-7, you will NOT be using the data file your instructor gave you.Please follow the instructions given in each question. Plotting the Binomial Probabilities For the next part of the lab, open the Week 3 Excel worksheet.This will be used for the next few questions, rather than the data file used for the first question. Click on the “binomial tables” workbookType in n=10 and p=0.5; this simulates ten flips of a coin where x is counting the number of heads that occur throughout the ten flipsCreate a scatter plot, either directly in this spreadsheet (if you are comfortable with those steps), or by using the Week 1 spreadsheet and copying the data from here onto that sheet (x would be the x variable, and P(X=x) would be the y variable.Repeat steps 2 and 3 with n=10 and p=0.25Repeat steps 2 and 3 with n=10 and p=0.75In the end, you will have three scatter plots for the first question below. Calculating Descriptive Statistics Short Answer Writing Assignment – Both the calculated binomial probabilities and the descriptive statistics from the class database will be used to answer the following questions.Round all numeric answers to three decimal places. P(x=0) P(x=6) P(x=1) P(x=7) P(x=2) P(x=8) P(x=3) P(x=9) P(x=4) P(x=10) P(x=5) P(x≥1) P(x<0) P(x>1) P(x≤4) P(4<x ≤7) P(x<4 or x≥7) Mean = np: Standard Deviation = : Mean = np: Standard Deviation = : Comparison: Mean = np: Standard Deviation = : Comparison: NOTE:For questions 8-9, you will use the results of the previous questions.
