Problem 1. (10 points) Consider the computer output shown below. Two-Sample t-Test and CI: Y1, Y2 TWO-sample T for vi vs Y2 N Mean Std. Dev. Y1 2e 50.19 1.71 Y2 20 52.52 2.48 SE Mean .38 0.55 Difference - mu (X1) - mu (X2) Estimate for difference: -2.33341 95% CI for difference: (-3.69547, -0.97135) T-Test of difference - (vs not -): T-Value - -3.47 p-Value - 0.081 DF = 38 Both use pooled Std. Dev. = 2.1277 (a) Can the null hypothesis be rejected at the 0.05 level? Why? (b) Is this a one-sided or two-sided test?
