The mean waiting time at the drivethrough of a fastfood restaurant from the time an order is placed to the time the order is received is 86.4 seconds. A manager devises a new drive-through system that she believes will decrease wait time. As a test, she initiates the new system at her restaurant and measures the wait time for 10 randomly selected orders. The wait times are provided in the table to the right.

Conduct a hypothesis test using the Pavalue approach and a level of signicance of or = 0.05. First determine the appropriate hypotheses. H0: v verso. H1: v v 36.4 Find the test statistic. (Round to two decimal places as needed.) Find the P-value. The Pvalue is . (Round to three decimal places as needed.) Use the or = 0.05 level of signicance.
