Extracted text: .A department store gives in-service training to its salesmen which is followed by a test. It is čonsidering whether it should terminate the services of any salesman who does not do well in the test. The following data gives the test scores and sales made by nine salesmen during a certain period: Test Scores Sales (*00 14 31 19 36 24 48 21 37 26 22 50 45 15 33 20 41 19 39 Calculate the coefficient of correlation between the test scores and the sales. Does it indicate that the termination of services of low test scores is justified ? If the firm wants a minimum sales volume of 3,000, what is the minimum test score that will ensure continuation of service ? Also estimate the most probable sales volume of a salesman making a score of 28.
