Use the traditional method to test the given hypothesis. Assume that the population is normally distributed and that the sample has been randomly selected.
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 $927.© BrainMass Inc. brainmass.com June 4, 2020, 2:30 am ad1c9bdddf
