The Rocky Mountain district sales manager of Rath Publishing
Inc., a college textbook publishing company, claims that the sales
representatives make an average of 37 sales calls per week on
professors. Several reps say that this estimate is too low. To
investigate, a random sample of 32 sales representatives reveals
that the mean number of calls made last week was 38. The standard
deviation of the sample is 2.4 calls. Using the .10 significance
level, can we conclude that the mean number of calls per
salesperson per week is more than 37?
