Table 8E.4 presents data on the waiting time in minutes) to see a nurse or physician in a hospital emergency department. Prepare a normal probability plot of these data. The hospital has a policy of seeing all patients initially within ten minutes of arrival.
(a) Prepare a normal probability plot of these data. Does the normal distribution seem to be an appropriate model for these data?
(b) Prepare a normal probability plot of the natural logarithm of these data. Does the normal distribution seem to be an appropriate model for the transformed data?
(c) Based on the data in Table 8E.4 and the normal probability plots, what proportion of the patients will not see a nurse or physician within 10 minutes of arrival?
