i Recently, a pizza place was receiving complaints about erratic pizza delivery times. To * 1?: address this issue, the owners made some operational changes in its restaurant and added 34 39 13 more delivery people to its staff. To study these changes, the owners would like to test the 35 29 41 hypothesis that the standard deviation for the delivery times of its pizza is less than 18 35 16 27 minutes. The data shown to the right represent a random sample of delivery times (in 38 15 10 minutes). Compiete parts a and b. 11 2 10 {EDw 3. Using a = 0.05, test whether or not the pizza place's goal was achieved. Identify the null and alternative hypotheses. Ho: 0'2 D H1: 02 El (T ype integers or decimals.) Calculate the appropriate test statistic. The test statistic is (:1. (Round to two decimal places as needed.) Determine the appropriate critical value(s). The critical value(s) is(are) [:].
