Concept explainers
You wish to test the following claim (HaHa) at a significance level of α=0.10. For the context of this problem, μd=PostTest−PreTest where the first data set represents a pre-test and the second data set represents a post-test. (Each row represents the pre and post-test scores for an individual. Be careful when you enter your data and specify what your μ1 and μ2 are so that the differences are computed correctly.)
Ho:μd=0
Ha:μd≠0
