WebMay 4, 2024 · To determine the appropriate critical value we need the sample size, which is equal to the number of matched pairs (n=8) and our one-sided level of significance α=0.05. For this example, the critical value is 1, and the decision rule is to reject H 0 if the smaller of the number of positive or negative signs < 1. We do not reject H 0 because 2 ...
