Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably norma distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom use Find the endpoints of the t-distribution with 2.5 % beyond them in each tail if the samples have sizes n₁ = 15 and n₂ = 20. Enter the exact answer for the degrees of freedom and round your answer for the endpoints to two decimal places. degrees of freedom = 14 endpoints = + i
