The average age of licensed drivers in a county is (population mean = 42.6), (population standard deviation =12), and the distribution is approximately normal. A county police officer was interested in whether the average age of drivers recieving speeding tickets differed from the average age of the driving population. she obtained a sample of N=16 drivers recieving speeding tickets. The average age for this sample was M=34.4. Perform the six steps of hypothesis testing (outlined below) necessary to determine whether this group differs from the population of drivers in the county (using an alpha level of p< .05). athen, calculate the 95% confidence interval and effect size.
