A sample of 25 patients in a doctor's office showed that they had to wait for an average of 35 minutes with a standard deviation of 10 minutes before they could see the doctor. Provide a 98% confidence interval estimate for the average waiting time of all the patients who visit this doctor. Assume the population of waiting times is normally distributed.

In a random sample of 25 patients in the emergency room, the sample mean waiting time before being seen by a doctor was 28 minutes with a sample standard deviation of 6 minutes. Assume waiting times are approximately normal. Compute a 90% confidence interval for the mean waiting time for all patients to be seen by a doctor.
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 test statistic?
