A sales manager for a large corporation claims that the average number of contacts made by the sales persons in the corporation is no more than 16 per week. As a check on this claim, a random sample of 36 sales persons is selected and the number of contacts made by each is recorded for a single randomly selected week. The mean and standard deviation of these 36 measurements were calculated to be 17 and 3 respectively. Test whether there is any evidence to support the sales manager's claim at the 5% level of significance.

4. A vice president in charge of sales for a large corporation claims that salespeople are averaging no more than 15 sales contacts per week. As a check on his claim, a sample size of 36 sales people are selected at random, and the number of contracts made by each is recorded for a single randomly selected week. From the sample the mean was found to be 17 and the standard deviation was found to be 3. At α = .05 is there enough evidence to support the researcher’s claim?

A vice president in charge of sales for a large corporation claims that salespeople are averaging no more than 15 sales contacts per week. (He would like to increase this figure.) As a check on his claim, n=26 salespeople are selected at random, and the number of contacts made by each is recorded for a single randomly selected week. The mean and variance of the 26 measurements were 11 and 9, respectively. Does the evidence support the vice president's claim? Use a test with a level of 0.05. Use the six-step hypothesis testing method.

A sales manager for an advertising agency believes there is a relationship between the number of contacts and the amount of sales. To verify this belief, the following data was collected: sales person | Numbers of contacts | sales (in thousands) 1 | 14 | 24 2 | 12 | 14 3 | 20 | 28 4 | 16 | 30 5 | 46 | 80 6 | 23 | 30 7 | 48 | 90 8 | 50 | 85 9 | 55 | 120 10 | 50 | 110 The standard deviation of the variable sales (in thousands) is about: 16.777 17.684 24.854 37.748 39.790
