WebUnder scenario (1), Δ ˜ reduces to Δ 1 = μ 11 − μ 01 and the overall hypothesis H 0 corresponds to the same overall hypothesis in the two‐trial paradigm with identical populations H 0 1. The null and alternative hypothesis regions for the two approaches are shown in Figure 1a . WebThus, the null hypothesis is H 0: μ ≤ 23.8 and the alternative hypothesis is H a: μ > 23.8. Explanation: By taking the greater than in alternative and less than or equal to in null hypothesis, the hypothesis is obtained.
Webμ = 25,000 . Null hypothesis is defined as the statement with no difference between two population parameters. It is denoted as H 0. According to the above question, in order to test whether the average family income in a community exceeds $25000, the appropriate null hypothesis is defined as: H 0: μ =25000. where μ : Population mean. WebOne of the most accessible and useful statistical tools for comparing independent populations in different research areas is the coefficient of variation (CV). In this study, first, the asymptotic distribution of the ratio of CV of two uncorrelated populations is investigated. Then, the outputs are used to create a confidence interval and to establish a test of …
