(d) Considering only offices without a wait tracking system, what is the z-score for the tenth patient in the sample? (Round your answer to two decimal places.) (e) Considering only offices with a wait tracking system, what is the z-score for the sixth patient in the sample? (Round your answer to two decimal places.) How does this z-score compare with the z-score you calculated for part (d)? As indicated by the z-scores, both patients had wait times that the means of their respective samples. Even though the patients had the same wait 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 a standard deviation.

Question
PLEASE ONLY RESPOND TO PART D, E, AND F THE REST HAS BEEN SOLVED
The average waiting time for a patient at an El Paso physician's office is just over 29 minutes, well above the national average of 21 minutes. In order to address the issue of long patient wait times, some physician's offices are using wait 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 wait times (minutes) for a sample of patients at offices that do not have an office tracking system and wait times for a sample of patients at offices with an office tracking system.

What are the variance and standard deviation (in min) of patient wait times for visits to offices without a wait tracking system? (Round your answers to one decimal place.)
variance standard deviation min
(c)
Do offices with a wait tracking system have shorter patient wait times than offices without a wait tracking system? Explain.
Offices with a wait tracking system have patient wait times than offices without a wait tracking system.
(d)
Considering only offices without a wait tracking system, what is the z-score for the tenth patient in the sample? (Round your answer to two decimal places.)
(e)
Considering only offices with a wait tracking system, what is the z-score for the sixth patient in the sample? (Round your answer to two decimal places.)
How does this z-score compare with the z-score you calculated for part (d)?
As indicated by the z-scores, both patients had wait times that the means of their respective samples. Even though the patients had the same wait 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 a standard deviation.
(f)
Based on z-scores, do the data for offices without a wait tracking system contain any outliers?
The data for offices without a wait tracking system contains outliers.
Based on z-scores, do the data for offices with a wait tracking system contain any outliers?
