The value of a sports franchise is directly related to the amount of revenue that a franchise can generate. The accompanying data table gives the value and the annual revenue for 15 major sport teams. Suppose you want to develop a simple linear regression model to predict franchise value based on annual revenue generated. Complete parts (a) through (e) below, Click the icon to view the table of franchise values and annual revenues. b0=-300.98 b1=3.33 (Round to two decimal places as needed.) c. Interpret the meaning of b0 and b1 in this problem. Choose the correct answer below. A. The Y -intercept, b0, implies that if the annual revenue is zero, the franchise value is equal to the value of b0, in millions of dollars. The slope, b1, implies that the average franchise value is equal to b1, in millions of dollars. B. An interpretation of the Y-intercept, b0, is not meaningful because no sports franchise is going to have a revenue of zero. The slope, b1, implies that for each increase of 1 million dollars in annual revenue, the franchise value is expected to increase by b1, in millions of dollars. c. The Y-intercept, b0, implies when the annual revenue is zero, the franchise value is b0, in millions dollars. The slope, b1. implies the revenue is equal to b1, in millions of dollars. D. The Y -intercept, b0, implies that if the annual revenue is zero, the franchise value is equal b0, in millions of dollars. The slope, b1, implies that for each increase of 1 million dollars in annual revenue, the franchise value is expected to decrease by b1, in millions of dollars. d. Predict the mean franchise value (in millions of dollars) of a sports team that generates 200 million of annual revenue. Y^=s million (Round to the nearest integer as needed.)
Elaine is interested in determining if men are more satisfied in their jobs than women in the healthcare industry. She administers a job satisfaction questionnaire to 20 men and 20 women working in hospital administration. Her grouping variable is gender and dependent variable is job satisfaction. The job satisfaction scale consists of 8 items measured using a 5-point rating scale. A higher score on this scale would indicate high job satisfaction. The maximum score that can be obtained on the scale is 40. We can assume that job satisfaction scores are normally distributed. Use the appropriate T test with a significance level of 0.05 to test the hypothesis. Research Question Do the mean job satisfaction scores differ for men and women working in the hospital administration department? Hypothesis The mean job satisfaction scores do not differ for men and women working in the hospital administration department. 1. Compute an independent sample test on these data. Report descriptive statistics (Mean and Standard deviation), t values, and p values. 2. Create a graph to show the differences between the two groups. 3. Write a Results section based on your analysis. Interpret results of the independent sample test to answer the research question and the hypothesis. Use APA style for describing the results. Submit the SPSS output file in a PDF to show the work you have done. submit a separate Word file describing the results in APA. Incorporate table(s) and figure/graph(s) in the Word document formatted in APA.
