3. Power Probability that a fixed level alpha significance test will reject H 0 when a particular alternative value of the parameter is true. 1. State H 0, H a, the particular alternative we want to detect, and significance level alpha 2. Find rejection region of sample statistic (ex, proportion) 3. Calculate P( observing these value of sample statistic when alternative is true)

4. Increasing power Increase alpha Consider a particular alternative that is farther away from null hypothesis Increase sample size Decrease sigma
