Michael Scott has been tasked with seeing how sales of paper at Dunder Mifflin is going. Sales are currently at an average of 14 per day, with a standard deviation of 4 (the distribution of sales follows a normal curve). Jan, his boss, wants to know whether the sales has to do with Jim and Pam's new sales technique. She wants to know whether sales have worsened due to their new sales technique. They test this technique on Andy, whose sales are at an average of 5. Using the .05 significance level, what should the Michael tell Jan? Solve this problem explicitly using all five steps of hypothesis testing and illustrate your answer with a sketch showing the comparison distribution, the cutoff (or cutoffs), and the score of the sample on this distribution.

Solve this problem explicitly using all ve steps of hypothesis testing and illustrate your answer with a sketch showing the comparison distribution, the cutoff (or cutoffs), and the score of the sample on this distribution. 0 Restate the question as a research hypothesis and a null hypothesis about the populations. 9 Determine the characteristics of the comparison distribution. 6 Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected. 0 Determine your sample's score on the comparison distribution. 6 Decide whether to reject the null hypothesis
