Consider the following hypothesis test. H0: μ1 − μ2 = 0 Ha: μ1 − μ2 ≠ 0 The following results are from independent samples taken from two populations assuming the variances are unequal. Sample 1 Sample 2 n1 = 35 n2 = 40 x1 = 13.6 x2 = 10.1 s1 = 5.8 s2 = 8.2

(a) What is the value of the test statistic? 2.153 correct

(b) What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.)
