An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has an unknown population standard deviation. By surveying randomly selected local hospitals, a researcher was able to obtain a sample of incubation periods of 40 patients with the average of the data of 9 days and the standard deviation of 3 days. At 10% significance level, test the claim that the average incubation period of the novel coronavirus is different from 7 days.
