You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the drive through window for branches in your geographical region, as measured from the time a customerplaces an order until the time the customer receives the order, was 38 minutes. You select a random sample of 81 orders. The sample mean waiting time is 367 minutes, with a sample standard deviation of 0 96minute Complete parts (a) and (b) belowa. At the 0.05 level of significance, is there evidence that the population mean waiting time is different from 38 minutes? State the null and atemative hypothesesH₂ PH₁ PY(Typo integers or decimals)

Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is ? = 19 inches. However, a survey reported that of a random sample of 51 fish caught, the mean length was x = 18.6 inches, with estimated standard deviation s = 2.9 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than ? = 19 inches? Use ? = 0.05. i-What is the value of the sample test statistic? (Round your answer to three decimal places.)
