The average age for licensed drivers in a county is u = 42.6, sd= 12, and the distribution is

approximately normal. A county police officer was interested in whether the average age of drivers receiving speeding tickets differed from the average age of the driving population. She obtained a sample of N= 16 drivers with speeding tickets. The average age for this sample was M= 34.4 and alpha = 0.05. (a) Calculate the effect size for this study. (b) calculate the statistical power for this study. (c) Does this statistical power meet the minimum criterion for statistical power to detect an effect?
