1. The P-value for a two sided test of the null hypothesis H0: µ = 30
... 1. The P-value for a two sided test of the null hypothesis H0: µ = 30 is 0.04. a) Does the 95% confidence interval include the value 30? Why? No. A 95% confidence interval corresponds to a hypothesis test with significance level of .05. A 95% confidence interval contains the hypothesized value o ...

Overview for Confidence Intervals and Hypothesis
... 1. Confidence Interval Method (uses a confidence interval to measure strength of evidence) This method uses a confidence interval to create a feasible region for the unknown parameter using sample data. If the confidence interval contains the hypothesized value then this would support a conclusion t ...
