WebAs you can see, our work suggests that for a given value of the mean \(\mu\) under the alternative hypothesis, the larger the sample size \(n\), the greater the power \(K(\mu)\). Perhaps there is no better way to see this than graphically by plotting the two power functions simultaneously, one when \(n=16\) and the other when \(n=64\): WebIn a clinical trial of a new drug, the null hypothesis might be that the new drug is no better, on average, than the current drug. We would write H0: there is no difference between the two drugs on average. The alternative hypothesismight be that: the new drug has a different effect, on average, compared to that of the current drug.
