18. Mayors' Salaries: The average salary of mayors of Canada's cities is reported to be equal to $120,000. To test this claim, 5 Canadian cities are selected and it is found that the average salary is $132,389. Assume the population standard deviation is $12,121. Using α = 0.05, test the claim that the reported salary is incorrect.

Recently, ESPN reported that the average salary of an NFL place-kicker is $1.9 million, while the average salary for an NFL running back is only $1.7 million. This statistic was cited as evidence that, in the current NFL, running backs are considered less valuable than place-kickers. The claim being made based on this statistic is misleading. In what way? (Hint: Teams have 1 place-kicker and, usually, 5 or 6 running backs, one of whom is their lead back.)
