In one town, monthly incomes for all men without college degrees are found to have a standard deviation of $650. Use a 0.01 significance level to test the claim that for men with college degrees in that town, incomes have a standard deviation above $650. A random sample of 27 men with college degrees resulted in incomes with a standard deviation of $825.
