1. A district sales manager of a college textbook publishing company claims that the sales representatives make an average of 40 sales calls per week. Several representatives claim the estimate is too low, and the number of calls is higher. To investigate, a random sample of 36 sales representatives is selected. In this random sample of 36 , the mean number of calls per sales representative is 42 . Historical data has shown that the population standard deviation is 4.1 calls. Can you conclude at the $5\%$ level of significance that the mean number of sales calls per representative is more than 40 ? a) Set up the hypotheses using a one-sided test. b) Identify the critical values and acceptance and rejection regions on a graph. c) Evaluate the proper standardized statistic. d) State your conclusion. e) Find the p-value for the test.
