In several exercises in this chapter, we considered the study of one week of a college football season, during which the population of 53 FBS games had a mean spread (winning score minus losing score) of 16.189, with a standard deviation of 12.128. The sample of 4 games that were played that week in the next-highest league, the FCS, had a mean of 8.75.

b What does the statistical power suggest about how we should view the findings of this study?

c. Using G*Power or an online power calculator, calculate statistical power for this study for a one-tailed

test with a p level of 0.05
