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 a sample of incubation periods of 34 patients and the sample average was found to be 7.16 days. Assume that the population standard deviation is 1.6 days. Choose the appropriate procedure for constructing a 90% confidence interval for the mean incubation period of the novel coronavirus. i. Procedure: Select an answer Select an answer One variance x² procedure One mean T procedure One mean Z procedure One proportion Z procedure ii. Assumptions: (select everything that applies) Sample size is greater than 30 O Population standard deviation is unknown Simple random sample Population standard deviation is known Normal population The number of positive and negative responses are both greater than 10 Select an answer Select an answer μ, population mean iii. Unknown parameter: p, population proportion o², population variance
