... (4pts)A comparison of two groups , A and B, was conducted using two samples. Sample one, from A, had a sample size of 20. Sample two, from B, had a sample size of 26. Given H0: A = B , H1: A≠ B, a significance level of 0.05, and a test statistic for the difference t= 2.0, find a p value and stat ...

... is based on a distribution of sample means for all possible random samples. This distribution is called a Sampling Distribution. It describes the variability of sample means that could occur just by chance and thereby serves as a frame of reference for generalizing from a single sample mean to a pop ...

... places and the P-value to 3 significant figures. You should report these t-test results as t92 = -7.1215, P = .000000000116 (left-tailed). Note that I included the degrees of freedom as a subscript; this is necessary because there is a different t distribution for each number of degrees of freedom. ...
