(1 point) Two independent samples have been selected, 57 observations from population 1 and 68 observations from population 2. The sample means have been calculated to be x1 = 13.5 and x2 = 13.3. From previous experience with these populations, it is known that the variances are o = 38 and ož = 24. = = For the hypothesis test of Ho : (uy-u2) = 2 and H,:(uy-uz) + 2 Use a= 0.05. (a) Compute the test statistic. Z= (b) Find the approximate p-value p-value = The final conclustion is - O A. We can reject the null hypothesis that (M - M2) = 2 and accept that (M1 – M2) #2 OB. There is not sufficient evidence to reject the null hypothesis that (un - H2) = 2
