A foreign car manufacturer advertises that its newest model, the Bullet, rarely stops at gas stations.  In fact, they claimed that its EPA rating for highway driving is at least 32.5 mpg. However, the  results of a recent independent study determined the mpg for 50 identical models of the Bullet,  with these results: n = 50,  x = 30.4 mpg, and s = 5.3 mpg. This report failed to offer any conclusion, and you have been asked to interpret these results by  someone who has always felt that the 32.5 figure is too high. What would be your conclusion  using a significance level of 5%?
