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.
1. 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.
