A simple random sample of 40 recorded speeds (in mi/h) is obtained from cars traveling on a section
of Highway 805 in Los Angeles. The sample has a mean of 68.4 mi/h and a standard deviation of 5.7
mi/h (based on data from Sigalert). Use a 0.05 significance level to test the claim that the mean speed
of all cars is greater than the posted speed limit of 65 mi/h.
