How to solve hypothesis testing
WebHypothesis Test for One-Sample Mean Recall that under certain conditions, the sampling distribution of the sample mean, x ¯, is approximately normal with mean, μ, standard error σ n, and estimated standard error s n. Null: H 0: μ = μ 0 Conditions: The distribution of the population is Normal The sample size is large n > 30. Test Statistic: WebHypothesis testing applications with a dichotomous outcome variable in a single population are also performed according to the five-step procedure. Similar to tests for means, a key component is setting up the null and research hypotheses. The objective is to compare the proportion of successes in a single population to a known proportion (p 0 ...
