Find the area in a t-distribution less than1.4 if the samples have sizes n 1 = 30
Question:
Find the area in a t-distribution less than−1.4 if the samples have sizes n1 = 30 and n2 = 40.
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.
