4. To test the null hypothesis that two population means satisfy #1 = /42 by using matched pairs with two samples of size n, we require that n > 30 and n 0. Suppose our null hypothesis is the population means agree (#1 = /2), that our sample size is n = 500, and that we find d = -0.94 and sd = 2.81. i. If we use a right-tailed test, what is our alternative hypothesis: #1 # #2 ? #1 #2 ? ii. What would we conclude if we rejected the null hypothesis with a right-tailed test? iii. Can we reject the null hypothesis at level of significance o = 0.05, using a right-tailed test? iv. Can we reject the null hypothesis at level of significance o = 0.01, using a right-tailed test
