We want to test the hypothesis that the population variances are equal. The null hypothesis is

  Sample A Sample B
s2 40 96
n 8 9

a. σA2 = σB2

b. σA2 > σB2

c. σA2 < σB2 

d. SA2 = SB2

The test statistic (F value) for this problem equals (hint: sample with larger variance should be numerator)

a. 0.417

b. .843

c. 2.4

d. 1.500

At 95% confidence, the critical value for this problem equals

a. 4.9

b. .843

c. 2.4

d. 1.500

At 95% confidence, the null hypothesis

a. should be rejected

b. should not be rejected 

c. should be revised 

d. None of these alternatives is correct
