A chain of restaurants has historically had a mean wait time of 5 minutes for its customers. Recently, the restaurant added several very popular Espanol dishes back to their menu. Due to this, the manager suspects the wait time, J, has increased. He takes a random sample of 35 customers. The mean wait time for the sample is 5.1 minutes. Assume the population standard deviation for the wait times is known to be 1.1 minutes. Can the manager conclude that the mean wait time is now greater than 5 minutes? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis Ho and the alternative hypothesis H1. X Ho: DO OSO 0>0 H: 020 0-0 0+0 X ? (b) Perform a hypothesis test. The test statistic has a normal distribution (so the test is a "Z-test"). Here is some other information to help you with your test. . Zo.10 is the value that cuts off an area of 0.10 in the right tail. . The test statistic has a normal distribution and the value is given by z = x -H Standard Normal Distribution Step 1: Select one-tailed or two-tailed. One-tailed O Two-tailed 03+
