Central Ohio Technical College Data Driven Decision Making Questions
Please solve the hypothesis testing problems (#1, and 2) using Minitab as the tool. For each problem, (1) specify the business and statistical hypotheses, (2) specify what the Type I and Type II errors are in this business context, and, the implications of making those errors, (3) include the results from Minitab, (4) draw appropriate conclusions to your statistical hypotheses based on the results, and, finally, (5) present the business conclusions in a short non-statistical summary. For problem 3, use Minitab and follow instructions given with the problem. For problem 4, several analyses will be necessary. Present each analysis with business/statistical hypotheses, Minitab results, and business conclusions. Incorporate those analyses into a short report.
Suppose Smith and Wilson is a relatively small West Coast advertising agency. Assume that they have hired you to help in their newly established advertising research department. Your first task is to evaluate the results of a copy test for a new consumer product. Three different versions of the advertisement were prepared. A random sample of 10 viewers watched the three versions. After each commercial was shown, each consumer’s attitude toward the product was measured on a scale of 1 to 100 (the higher the score, the more favorable the attitude). The scores of the 10 viewers are below:

After receiving your bachelor’s degree in personnel management, you were hired by a small but expanding life insurance company. Your first assignment is to develop a more efficient technique for the preliminary screening of applicants for sales positions. Since the firm employs only college graduates, you decide to work with information focusing on their performance during college.
A random sample of 25 from the firm’s current sales force is selected and the following information is obtained:
Last year’s performance evaluation score
College grade point average (GPA)
Percent of total college expenses earned by the individual
Number of social organizations the individual belonged to

On the basis of the data obtained, what recommendations can you make regarding the preliminary screening of applicants for sales positions?
3. A contractor has recorded the number of jobs performed in the last seven months.
a.Draw a graph of the number of jobs (as y) and time (as x). Be sure to label the axes.
For each of the following methods, develop a forecast for the number of jobs for the 8th month.
b.A three-period moving average
c.Exponential smoothing (use Minitab default smoothing parameters)
d.A linear trend equation
Using the mean squared difference (MSD), explain which of the methods you believe results in the best forecast and make your recommendation to the contractor about what he should expect for the eighth month.

Grantham University W7 Coefficient of Determination Worksheet
Week 7 AssignmentQuestion 1Assume you have noted the following prices for paperback books and the number of pages that each book contains.Develop a least-squares estimated regression line.Compute the coefficient of determination and explain its meaning.Compute the correlation coefficient between the price and the number of pages. Test to see if x and y are related. Use α = 0.10.Question 2The following data represent a company's yearly sales volume and its advertising expenditure over a period of 8 years.Develop a scatter diagram of sales versus advertising and explain what it shows regarding the relationship between sales and advertising.Use the method of least squares to compute an estimated regression line between sales and advertising.If the company's advertising expenditure is $400,000, what are the predicted sales? Give the answer in dollars.What does the slope of the estimated regression line indicate?

Stanford University Probability Distributions Calculations
Imagine if you were offered a job in a different state and a major consideration for you is rent prices (assuming you planned to rent instead of buy). Your main concerns are the affordability in relation to your income and the location/condition of the property. Perhaps you would look for the cheapest rent possible within a quiet, residential community. Or, you might be willing to spend at little more than average to live in the heart of downtown. As you research the city, you learn that the mean for rents of your preferred home size are $1,300 a month. Many people might base their decision on this number alone, but you—equipped with the knowledge of standard deviation—know there is more to that number.If the most you could afford is $1,100 a month in rent, then a standard deviation of $250 might be good news because the amount you can afford is still within 1 deviation of the mean. With a standard deviation of $75, however, you might be unwilling to make the sacrifices necessary to rent a place that you could afford. Additionally, if you were willing to spend a little more than average to live in a nice place or area, then you could easily find an amazing place with a standard deviation of $100 but might not be able to afford the upgrade with a standard deviation of $300.In this Discussion, you will use the data that you gathered in the Week 1 Discussion to calculate a standard deviation and explain how this concept can affect decision making.To prepare for this Discussion:Review this week’s Learning Resources.Locate the data that you gathered for the Week 1 Discussion.Calculate the sample standard deviation from your cigarette price data in Week 1. Use that (and your sample average and sample size) to calculate the following (assuming a normal distribution):Within what range would you find 90% of cigarette prices in your area?What are the chances that someone in your area would pay 4 dollars or less per pack?What are the chances that someone in your area would pay 10 dollars or less per pack?Review the Academic Writing Expectations for 2000/3000-Level Courses, provided in this week’s Learning Resources.BY DAY 3Post a 150- to 225-word (2- to 3-paragraph) explanation of how probability distributions affect management decisions. In your explanation, address the following:Provide your results of the following:Your calculations for your standard deviationThe range within which 90% of the prices of cigarettes in your area fallsThe chances of anyone paying less than 4 dollars for a pack of cigarettesThe chances of anyone paying more than 10 dollars for a pack of cigarettesDescribe what implications this concept has for management decision making.Explain how you might use information like this in your current work.To support your response, be sure to reference at least one properly cited scholarly source.
