According to government figures, the average age of a male federal public servant is 43.6 years and of a male state public servant is 37.3 years. Is there any difference between the variations of ages of men in the federal sector and men in the state sector? Suppose a random sample of 15 male federal workers is taken and the variance of their ages is 91.5. Suppose also that a random sample of 15 male state workers is taken and the variance of their ages is 67.3. Use these data and α = 0.01 to answer the question. Assume that ages are normally distributed.
