Perform the required chi-square hypothesis test. Preliminary data analyses and other information indicate that it isreasonable to assume that the variable under consideration is normally distributed. Use the critical-value approach or theP-value approach as indicated.
-In one town, monthly incomes for men with college degrees are found to have a standard deviation of $650. A random sample of 22 men without college degrees resulted in incomes with a standard deviation of $905. At the 1% level of significance, do the data provide sufficient evidence to conclude that the standard deviation, Ϭ, of incomes of men in that town without college degrees is greater than $650? Use the critical-value approach.
