Consider the following hypothesis test. Ho: M1 - M2 = 0 На: 11 - 2 + 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 ni = 35 n2 = 40 x1 = 13.6 2 = = 10.1 Su = 5.6 S2 = 8.5 (a) What is the value of the test statistic? (Use x1 - x2. Round your answer to three decimal places.) (b) What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.) (c) What is the p-value? (Round your answer to four decimal places.) p-value = (d) At a = 0.05, what is your conclusion? Do not Reject Ho. There is sufficient evidence to conclude that hi - U2 0. Reject Ho. There is insufficient evidence to conclude that H1 - H2 = 0. O Do not Reject Ho. There is insufficient evidence to conclude that uy - M2 + 0. Reject Ho. There is sufficient evidence to conclude that wy - 42 0.
