I got this backward. C at the top and A at the bottom. Sorry.

Do a two-sample test for equality of means assuming unequal variances. Calculate the p-value using Excel. (a-1) Comparison of GPA for randomly chosen collegejuniors and seniors: i1 = 4.05, 51 = .20, n1 =15, 372 = 4.35, 52 = .30, n2 =15, a = .025, left-tailed test. (Negative values should be indicated by a minus sign. Round down your dJE answer to the nearest whole number and other answers to 4 decimal places. Do not use "quick" rules for degrees of freedom.) d.f. tcalculated pvalue t-critical (a-2) Based on the above data choose the correct decision. T?
