You may need to use the appropriate technology to answer this question. Consider the following hypothesis test. Hoi ly- Hz = 0 H3i Hy- Hz#0 The following results are from independent samples taken from two populations assuming the variances are unequal. Sample 1 Sample 2 n = 35 n2 = 40 = 13.6 x, = 10.1 s, = 5.8 S2 = 8.9 (a) What is the value of the test statistic? (Use x, - x,. 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? O Reject H. There is sufficient evidence to conclude that u, - u, + 0. Do not Reject H. There is sufficient evidence to conclude that µ, - µ, # 0. Do not Reject H,. There is insufficient evidence to conclude that H, - µ, # 0. Reject H,. There is insufficient evidence to conclude that u, - µ, + 0.
