Independent random samples were selected from each of two normally distributed populations, n1 = 16 from population 1 and n2 = 25 from population 2. The means and variances for the two samples are shown in the following table.

a. Test the null hypothesis H0: s1 2 = s2 2 against the alternative hypothesis Ha: s1 2 s2 2 . Use a = .05.

b. Find and interpret the p-value of the test.
