Part 2 -

Complete the following four hypotheses, using = 0.05 for each.

1. Mean sales per week exceed 42.5 per salesperson

2. Proportion receiving online training is less than 55%

3. Mean calls made among those with no training is at least 145

4. Mean time per call is 14.7 minutes Using the same data set from part A, perform the hypothesis test for each speculation in order to see if there is evidence to support the manager's belief.

Use the Eight Steps of a Test of Hypothesis from Section 9.1 of your text book as a guide. You can use either the p-value or the critical values to draw conclusions. Be sure to explain your conclusion and interpret that to the claim in simple terms Compute 99% confidence intervals for the variables used in each hypothesis test, and interpret these intervals.
