An incubation period is a time between when you contract a virus and when your symptoms start. By
surveying randomly selected local hospitals, a researcher was able to obtain the sample of incubation
periods of 18 patients. The sample of incubation periods has a mean of 5.58 days and a standard deviation
of 1.23 days. Construct a 95% confidence interval for the average incubation period of the novel
coronavirus. You may assume that the sample is from a normal population.
