How to solve step by step

Carry out ALL 9 steps of the hypothesis testing procedure. 1. Assume that anxiety scores as measured by an anxiety assessment inventory are normally distributed with u = 20 and o = 4. A sample of 4 patients who are undergoing treatment for anxiety is randomly selected. and their mean anxiety score x = 22. Is the average anxiety score from patients who are under treatment significantly different from 20"? Assume a = .10 2. According to the National Association of Builders, the average single-family home size in United States is normally distributed with a mean u = 2392 square feet and a standard deviation o = 760 square feet. Sixty single-family houses are randomly selected from Cleveland, and the mean size is 2,025 square feet. Is the average square footage of houses Cleveland different than the population mean? Assume a = .05
