Score: 0.63 of 1 pt 18 of 20 (18 complete) HW Score: 76.04%, 15.21 of 20 pts 10.3.21-T Question Help The mean waiting time at the drive-through of a fast-food restaurant from the time an order is placed to the time the order is received is 88.3 seconds. A manager devises a new drive-through system 105.9 81.2 that he believes will decrease wait time. As a test, he initiates the new system at his restaurant and measures the wait time for 10 randomly selected orders. The wait times are provided in the table. 67.2 96.3 Complete parts (a) and (b) below. 57.1 84.0 75.8 71.6 67.1 83.8 (a) Because the sample size is small, the manager must verify that the wait time is normally distributed and the sample does not contain any outliers. The normal probability plot and boxplot are shown. Are the conditions for testing the hypothesis satisfied? A. Yes, the conditions are satisfied. 100- O B. No, the sample is not normally distributed. percent 50 C. No, the sample is not normally distributed and contains outliers. O D. No, the sample contains outliers. 55 85 115 55 115 time (seconds) time (seconds) (b) Is the new system effective? Conduct a hypothesis test using the P-value approach and a level of significance of a = 0.05. First determine the appropriate hypotheses. Ho: H = 88.3 H1 : H
