In one town, monthly incomes for men with college degrees are found to have a standard
deviation of $650. Use a 0.01 significance level to test the claim that for men without college
degrees in that town, incomes have a higher standard deviation. A random sample of 22 men
without college degrees resulted in incomes with a standard deviation of $926.
Select the correct conclusion based on the null hypothesis and final conclusion.
O Fail to reject Ho. There is not sufficient evidence to support the claim that incomes of men without
college degrees have a standard deviation greater than $650.
