An analyst is conducting a hypothesis test regarding the mean driving speed on the BQE during rush hour. The analyst wants to determine whether or not the mean observed speed is above the posted speed limit of 55 mph. The analyst collects data from a sample of 50 independent observations, including the standard deviation. The analyst sets the test as follows: H: u = 55; H1: u > 55 and computes a test statistic of 1.62. Assuming a significance level of 5%, the p-value for this test is close to 6% 11% 95% 49%
