Assume that you have a sample of n 1 equals 8n1=8, with the sample mean upper x overbar 1 equals 40x1=40, and a sample standard deviation of upper s 1 equals 7s1=7, and you have an independent sample of n 2 equals 4n2=4 from another population with a sample mean of upper x overbar 2 equals 38x2=38 and the sample standard deviation upper s 2 equals 6s2=6. assuming the population variances are equal, at the 0.010.01 level of significance, is there evidence that mu 1 greater than mu 2μ1> μ2? a) find the test statistic. b) find the p-value. c) choose the correct conclusion below. a. do not rejectdo not reject upper h 0h0. there is insufficientinsufficient evidence that mu 1 greater than mu 2μ1> μ2. b. do not rejectdo not reject upper h 0h0. there is sufficientsufficient evidence that mu 1 greater than mu 2μ1> μ2. c. rejectreject upper h 0h0. there is insufficientinsufficient evidence that mu 1 greater than mu 2μ1> μ2. d. rejectreject upper h 0h0. there is sufficientsufficient evidence that mu 1 greater than mu 2μ1> μ2.
