Problem 4aAt a 1% level of significance, conduct the appropriate test of hypothesis involving the population mean for Variable 5 in your survey. Create a right tailed test where you specify the hypothesized mean (feel free to specify any value for the population claim that makes sense given your data). In your answer make sure that you show H0 and Ha, sketch the sampling distribution showing the critical value(s) and the rejection region. Use your calculator to compute the test statistic and also state the decision and conclusion in the context of the survey. Show all your work .

Problem 4b What key assumption did you make in conducting the test in Problem 4a. Fully Explain.
