DllUW HLLEHIPL l'lthUly Current Attempt in Progress X Your answer is incorrect. Use a tdistribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a tstatistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a tdistribution less than 1.4 if the samples have sizes 111 = 30 and 11; = 40. Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. eTextbook and Media Hint
