The researcher expects a 12point treatment effect and plans to use a two-tailed hypothesis test with a = .05. Compute the power of the test if the researcher uses a sample of n = 16 individuals. (Note: Please report the result as a percentage, but do not include the percent sign. Otherwise, Brightspace will mark it wrong.)
