A life insurance salesperson claims the average worker in the city of Cincinnati has no more than $25,000 of personal life insurance. To test this claim, you randomly sample 100 workers in Cincinnati. You find that this sample of workers averages $26,650 of personal life insurance with a standard deviation of $12,000. Determine whether the evidence is enough to reject the salesperson's claim. Establish the Null and alternative hypothesis, and choose the right test statistics.
