In graphing power curves, there is a different power curve for each sample size n

True or false???>

Solution

True.

Larger sample size will increase power, ceteris paribus.

As n increases, so does the power of the significance test. This is because a larger sample size narrows the distribution of the test statistic. The hypothesized distribution of the test statistic and the true distribution of the test statistic (should the null hypothesis in fact be false) become more distinct from one another as they become narrower, so it becomes easier to tell whether the observed statistic comes from one distribution or the other.
