a pharmaceutical company is testing a new drug for reducing cholesterol levels. to approve the drug for the next round of testing, they need to show that this drug reduces mean total cholesterol level by at least 50 mg/dl. They initially plan a study that involves 50 subjects and a significance level of a=0.05, but they discover that the power of the test against this effect size is only 0.24. What are two ways they can increase the power of the test without changing effect size?
