DETAILS You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. Ho: M-42 - 0 Ho: M- My * 0 The following results are from independent samples taken from two populations assuming the variances are unequal. Sample 1 Sample 2 n2 - 40 *, - 13.6 13.6 72 - 10.1 $, - 5.8 52 - 8.3 (a) What is the value of the test statistic? (Use x - Xy. Round your answer to three decimal places.) 02 - 35 (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 jy - 42 + . Do not Reject Ho. There is insufficient evidence to conclude that N1 - 2 + 0. Reject Ho. There is sufficient evidence to conclude that 1 - 2 * 0. Reject Ho. There is insufficient evidence to conclude that M - M2 +0
