Question

View Policies Current Attempt in Progress Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that at- 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 n = 14 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 - i endpoints = + i e Textbook and Media Attempts: 0 of 3 used Save for Later Submit Answer Send to Gradebook < Prev Next >

I Ans. Hene, Here, n ni= 14 = 14, m2 = 20. - 20. degrees of freedom = not, -2= 14+20-2 = 32. End points of h to distribution with 2.5% beyond from the endpoints - in each tails with d.oof 32 . is nothing but T 10.025, 32) = I 2.0A 0.025 025
