1. The average age of licensed drivers in a county is m = 42.6, s = 12, and the distribution is approximately normal. A county police officer was interested in whether the average age of drivers receiving parking tickets differed from the average age of the driving population. She obtained a sample of N = 25 drivers receiving parking tickets. The average age of these drivers was M= 40.5. Perform the 5 steps of hypothesis testing necessary to determine whether this group differs from the population of drivers in the county.
