Statistics Homework Help

The average age of licensed drivers in a county is μ = 42.6, σ = 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 receiving speeding tickets. The average age for this sample was M = 34.4. Perform the six steps of hypothesis testing necessary to determine whether this group differs from the population of drivers in the county.
