What can be concluded from the hypothesis test? Image transcription textSubmi This question: 1 point(s) possible The mean wasting time of the drive-through of a fast-food restaurant from the time an order is placed to the time the order is received is 86 9 seconds. A manager devises a new drive through system that he believes will decrease 102.0 wail time As a test. he initiates the new system at his restaurant and measures the wail time for 10 randomly selected orders. The wait times are provided in the table to the right. Complete parts (a) and (b) below 687 94.4 572 86.3 74 4 646 82 4 BigClick the icon to view the table of correlation coefficient critical values. (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 outhers. The normal probability plot is shown below and the sample correlation coefficient is known to be r= 0.993. Are the conditions for testing the hypothesis satisfied? Yes. the conditions are satisfied. The normal probabatty plot is linear enough, since the correlation coefficient is lessthan the critical value. In addition, a boxplot does not show any outliers – X Critical values Sample Size, n Critical Value Sample Size, n Critical Value 5 0.880 18 0.941 0.688 (b) Is the new system effective?
