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 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 a wait-tracking...

Tommy Wait, a minor league baseball pitcher, is notorious for taking an excessive amount of time between pitches. In fact, his times between pitches are normally distributed with a mean of 33 seconds and a standard deviation of 2.7 seconds. What percentage of his times between pitches are longer than 38 seconds? Round your answer to two decimal places. The time between pitches is longer than 38 seconds _____% of the time.

The scores on an economics examination are normally distributed with a mean of 67 and a standard deviation of 12. If the instructor assigns a grade of A to 11% of the class, what is the lowest score a student may have and still obtain an A? (Round your answer to two decimal places.) You may need to use the appropriate table in the Appendix of Tables to answer this question.
