Emergency Room Traffic. Desert Samaritan Hospital in Mesa, Arizona, keeps records of emergency room traffic. Those records reveal that the times between arriving patients have a special type of reverse-J-shaped distribution called an exponential distribution. The records also show that the mean time between arriving patients is 8.7 minutes. a. Use the technology of your choice to simulate four random samples of 75 interarrival times each.b. Obtain a normal probability plot of each sample in part (a).c. Are the normal probability plots in part (b) what you expected? Explain your answer.
