1. For a test at a fixed significance level, and with given null and alternative hypotheses, what will happen to the power as the sample size increases? 2. For a test of a given null hypothesis against a given alternative hypothesis, and with a given sample size, describe what would happen to the power of the test if the signifi- cance level was changed from 5% to 1%. 3. A test of a given null hypothesis against a given alternative hypothesis, with a sample of size n and significance level of, has power of 80%. What change could I make to the test to increase my chance of rejecting a false null hypothesis? 4. How can we attain a test which has a very low probability of Type I error and also a uoru low probability of Type II error? 33°C Mostly sunny NO
