Independent random samples were selected from each of two normally distributed populations, n1, = 12 from population 1 and n2 = 27 from population 2. The means and variances for the two samples are shown in the table.

a. Test the null hypothesis H0: σ21 = σ22 against the alternative hypothesis Ha: σ21 > σ22. Use α = .10.
b. Find and interpret the approximate p-value of the test.
