The Power of a test is the probability of the test correctly rejecting a false null hypothesis.
How can you increase the power of a test?
[list=1]
[*] You can hope for an extreme sample (drag point A to the right).
[*] You can increase the alpha level, thus increasing the probability of rejecting the null hypothesis regardless of
it being false or not (drag point B to the left).
[*] You can increase the sample size (as long as it stays less than 10% of the population size).
