WebThe conclusion drawn from a two-tailed confidence interval is usually the same as the conclusion drawn from a two-tailed hypothesis test. In other words, if the the 95% confidence interval contains the hypothesized parameter, then a hypothesis test at the 0.05 \(\alpha\) level will almost always fail to reject the null hypothesis. WebAssume that all conditions for inference have been met. Based on the interval, what do we know about the corresponding P-value and conclusion at the alpha is equal to 0.01 level of significance?
