Extracted text: 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 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 5 % beyond them in each tail if the samples have sizes nį = 9 and n2 = 11. Enter the exact number for the degrees of freedom and round your answer for the endpoints to two decimal places. degrees of freedom = i 18 endpoints = ± i
