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 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 = proportion = i
