# Degree of Freedom and T-Distribution

Use the t-distribution table to find the critical value(s) for the indicated alternative hypothesis, level of significance ?, and sample sizes n? and n?. Assume that the samples are independent, normal, and random. Answer parts (a) and (b).

H?: µ? ? µ?, ? = 0.10, n? = 14, n? = 13

(a) Find the critical value(s) assuming the population variances are equal.

(b) Find the critical value(s) assuming that the population variances are not equal.
