The waiting time at the doctor's office has a normal distribution with a mean of 35 minutes and a standard deviation of 2.6. What is the probability of a patient waiting for at least 34 minutes but not more than 37 minutes? What is the probability of a patient waiting for more than 38 minutes? Determine the value of a waiting time such that the probability of waiting for less than that time is 45%.

Step 1
Probability of a patient waiting for at least 34 minutes but not more than 37 minutes: We need to find the area under the normal distribution curve between 34 and 37 minutes. We can use a standard normal distribution table or a calculator to find the z-scores for Show more…

The office manager of a doctor's office wants to evaluate how long patients are waiting in the waiting room for their appointment. They find that the mean wait time is 17.2 minutes and the standard deviation is 7.3 minutes. If the office manager takes a random sample of 40 patients, what is the probability that their mean wait time will be more than 15 minutes?

The average waiting time in a doctor’s office varies. The standard deviation of waiting times in a doctor’s office is 3.4 minutes. A random sample of 30 patients in the doctor’s office has a standard deviation of waiting times of 4.1 minutes. One doctor believes the variance of waiting times is greater than originally thought. What is the p-value?
