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 proportion in a t-distribution less than – 1.4 if the samples have sizes n1 30 and n2 40. Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = i proportion = i

Question
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 proportion in a t-distribution less than – 1.4 if the samples have sizes nị 30 and n2 :40. Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = i proportion = i
