Suppose that the average waiting time for a patient at a physician's office is just over 29 minutes. in order to address the issue of long patient wait times, some physicians' offices are using walt-tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wat times (minutes) for a sample of patients at offices that do not have a wait-tracking system and wait times for a sample of patients at offices with a wait-tracking system. (a) Considering only offices without a wait-tracking system, what is the z-score for the 10 th patient in the sample (wait time = 35 minutes)? If required, round your intermediate calculations and final answer to two decimal places. z5core= (b) Considering only offices with a wait-tracking system, what is the z-score for the 6th patient in the sample (wait time =35 minutes)? If required, round your intermedlate calculations and final answer to two decimal places. zscore= (8) How does this z5 core compare with the z-score you calculated for part (a)? Both patients had wait times that the means of their respective samples, as indicated by the z-scores. Even though the patients had the same wat time, the z-score for the sixth patient in the sample who visited an office with a wait tracking system is much because that patient is part of a sample with a mean and standard deviation
