QUESTION 2

Suppose a random sample of 8 male federal workers is taken and the variance of their ages is 91.5. Suppose also that a random sample of 9 male state workers is taken and the variance of their ages is 67.3. Find the lower critical value used to determine if there is any difference between the variations of ages of men in the federal sector and men in the state sector at the 5% level of significance (round your final answer to two decimal places). Assume population 1 = federal sector and population 2 = state sector. Assume that ages are normally distributed.
