Assume that you have a sample of n1 = 7, with the sample mean XBar X1 = 44, and a sample standard deviation of S1 = 5, and you have an independent sample of n2 = 14 from another population with a sample mean XBar X2 = 36 and sample standard deviation S2 = 6. a. What is the value of the pooled-variance tSTAT test statistic for testing H0:µ1 = µ2? b. In finding the critical value ta/2, how many degrees of freedom are there?
