Question: Prescott County Superintendent of Schools, John Chalk, has been concerned about his teachers. He knows that his new teachers graduating from the special training program at PCC earn their bachelor’s degree in elementary or secondary teaching, but they only start at the Prescott schools with a salary of $28,000 per year. The average teacher with the district earns $33,750 with a standard deviation of $1,250. In order to find out if the average salary of the teachers is the same as $33,750, Chalk scratches through the payroll records of 35 teachers in the district and finds that the mean salary equals $33,300.
