Assume the standard deviations of both populations are known. Consider the following hypothesis test with significance level a = 0.05. = Ho: M1 M2 = 0 Ha: M1 - M2 = 0 For sample 1, ni = 80, X1 = 104, 01 = 8.4 and for sample 2, n2 = 70, X2 = 106, = 02 = 7.6. = a) Find the test statistic. b) Use the critical value approach to reach your conclusion. c) What is the p-value of this test. What is your conclusion? d) Use the above information to construct a 97% confidence interval for M1 – U2.
