Consider the following hypothesis test. HO: H1 - H2 = 0 Ha: H1 - H2 * 0 The following results are from independent samples taken from two populations. Sample 1 Sample 2 n1 = 35 n2 = 40 x1 = 13.6 X2 = 10.1 51 = 5.3 52 = 8.8 (a) What is the value of the test statistic? (Use x, - x2. Round your answer to three decimal places. ) 1.995 X (b) What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.) 73 X (c) What is the p-value? (Round your answer to four decimal places.) p-value = 0.0498 X
