When testing H0: σ12 = σ22 vs. Ha: σ12 ≠ σ22 two random samples of sizes 10 and 8, respectively, are used. The calculated value of the test statistic is found to be equal to 2.22. Which of the following statements is true?

a. H0 must be rejected at α =.05.

b. H0 cannot be rejected at α =.05.

c. There is sufficient evidence at α =.05 to conclude that a difference in the population variances exist.

d. H0 cannot be rejected at α =.10.

e. none of these
