    The amount of time that you have to wait before seeing the doctor in the doctor's office is normally distributed with a mean of 15.2 minutes and a standard deviation of 15.2 minutes. If you take a random sample of 64 patients, what is the probability that the average wait time is greater than 20 minutes?

  • Suppose that the wait times for patients in an emergency room are normally distributed with an...

    Suppose that the wait times for patients in an emergency room are normally distributed with an unknown mean and standard deviation. A random sample of 18 patients is taken and gives a sample mean of 25 minutes and a sample standard deviation of 2 minutes. As found above, the EBM, margin of error, for a 95% confidence interval estimate for the population mean using the Student's t-distribution is 0.99. Find a 95% confidence interval estimate for the population mean using...

    The wait times to see a doctor at a large clinic are normally distributed with a mean of 68.2 minutes and a standard deviation of 14.8 minutes. If a simple random sample of 25 patients is selected, find the probability that the sample mean wait time is more than 75 minutes. Round to four decimal places.

    The R# Medical Centre undertook a survey to determine the average waiting time of patients in the surgery before they saw a doctor. From 12 responses, the average and standard deviation of the waiting times was found to be 14.1 and 11.84 minutes, respectively. Assuming the information was collected through a random sample and that the waiting time is approximately normally distributed, calculate a 98% confidence interval for the mean waiting time at the medical centre. State the lower bound...
