13. A doctor wants to create a 90% confidence interval to estimate the mean time between when a patient doesn't feel well and when they make an appointment with their office. Assume these times follow a normal distribution. What is the minimum sample size the doctor needs to collect to create their confidence interval to be within 5-hours of the true mean? Use a known standard deviation of B18-hours. Round your answer up to the next whole number.
