Score: 0 of 1 pt 1of8 (0 comlete) HW Score: 0%, 0 of 8 pts 8.2.5 Question Help Use the t-distribution table to find the critical value(s) for the indicated alternative hypotheses, level of significance a, and sample sizes n, and n2 Assume that the samples are independent, normal, and random. Answer parts (a) and (b). (a) Find the critical value(s) assuming that the population variances are equal (Type an integer or decimal rounded to three decimal places as needed. Use a comma to separate answers as needed)

Explanation / Answer

this is a t distribtion with degrees of freedom = n1 + n2 - 2 = 6 + 8 - 2 = 12

a) critical value = -t0.1,12 = -1.356
