Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the endpoints of the t-distribution with 2.5% beyond them in each tail if the samples have sizes n1 =15 and n2 =25 Enter the exact answer for the degrees of freedom and round your answer for the endpoints to two decimal places. Degrees of freedom = Endpoints = ±
