What would increase the power of this test? Check all that apply.

Power generally increases with a larger sample size because the test can detect smaller differences more reliably, so using n = 200 instead of n = 100 increases power. Raising the significance level α also increases power by making it easier to reject the null hypothesis when an effect is present. Thus, changing α from 0.01 to 0.1 or 0.05 increases power; reducing the sample size would decrease it.
