Exercise 2. A corporation administers an aptitude test to all new sales representatives. Management is interested in the extent to which this test is able to predict sales representatives' eventual success. The accompanying table records average weekly sales (in thousands of dollars) and aptitude test scores for a random sample of eight representatives. Test score Weekly Sales 55 60 85 75 80 85 65 60 10 12 28 24 18 16 15 12 a. Estimate the linear regression of weekly sales on aptitude test scores. b. Interpret the estimated slope of the regression line.
