1. School administrators believe their freshmanapplications are influenced by two variables: tuitionand the size of the applicant pool of eligible highschool seniors in the state. The following data for an8-year period show the tuition rates (per semester)and the sizes of the applicant pool for each year:Tuition in pesos Applicants Pool Applicants2700076,20011,0603750078,05010,9004125067,4208,6704200070,3909.0504650062,5507,4004875059,2307,1005250057,9006,3005790060,0806,100 a.

The accompanying data are the number of wins and the earned run averages (mean number of earned runs allowed per nine innings pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.

Emily is a fifth-grade student who completed a standardized reading test. She scored one standard deviation above the mean score. Answer the following questions: How does the normal curve help you understand what this means about how Emily compared to other children who took the test? Explain how you determined your findings. How many children scored lower than Emily? How many children scored higher?
The owner of Showtime Movie Theaters, Inc., used multiple regression analysis to predict gross revenue (y) as a function of television advertising (x 1) and newspaper advertising (x 2). The estimated regression equation was Weekly Gross Revenue ($1000s) Televison Advertising ($1000s) Newspaper Advertising ($1000s) 97 6 1.5 91 3 2 95 5 2.5 93 3.5 2.5 96 4 4.3 94 4.5 2.3 95 3.5 4.2 95 4 3.5 ŷ = 82.5 + 2.01 x 1 + 1.26 x 2The computer solution provided SST = 24 and SSR = 22.876. Compute R 2 and R a 2 (to 3 decimals). R 2 R a 2 When television advertising was the only independent variable, R 2 = 0.551 and R a 2 = 0.476. Are the multiple regression analysis results preferable?
