9. (Bonus 20) A random sample of n = 46 observations from a quantitative population produced a mean x = 2.37 and a standard deviation of s = 28. Your research objective is to show that the population mean y exceeds 2.29. Use this information to answer the questions below. a. Give the null and alternative hypotheses for the test. b. Calculate the test statistic for x = 2.42. c. Locate the rejection region for the test using a = .01. That is, find the critical value. d. Based on the critical value approach, determine if the data provide sufficient evidence to conclude that i exceeds 2.29?
