You have just determined the alpha level for a study that has these characteristics:

A sample of 40 individuals is randomly selected from a normal population with = 100 and = 25. Those individuals are treated, and the treatment is expected to increase scores by 6.2 points. You use a two-tailed hypothesis test with = .05 to see if the treatment is statistically significant.

Based on this information, what is the power associated with the statistical test?
