THESE QUESTIONS I NEED HELP THANKS Carry out all nine 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 the United States is normally distributed with a mean p = 2392 square feetand 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 in Cleveland different than the population mean? Assume a = .05 3.)A certain brand of tissues has 60 tissues in a standard box because the manufacturers believe that this is the average number of times people blow their nose during a cold. A research of the company checking on the validity of this claim, asked a random sample of 100 people to count the number of times they blow their nose during a cold. The mean of the sample was 57 and the standard deviation was 16. Do these data support the company's belief? Should the company continue to put 60 tissues in a box? Use a two-tailed hypothesis testing procedure with a of .05. Carry out all nine steps of the hypothesis testing procedure
