Due to this, the manager suspects the wait time, µ, has increased. He takes a random sample of 38 customers. The mean wait time for the sample is 6.4 minutes. Assume the population standard deviation for the wait times is known to be 3.1 minutes. Can the manager conclude that the mean wait time is now greater than 6 minutes? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis H, and the alternative hypothesis H,. H,: 0 O
