From each of the two normally distributed populations, independent random samples were selected. n1 =25 from population 1 and n2 = 11 from population 2. The below table gives the means and variances for the two samples:

Sample Size Mean Variance

Sample 1 25 35.4 8.15

Sample 2 11 30.2 3.47

To testH0: Variance 1 = Variance 2 versus H1: Variance 1 > Variance 2, Find F critical value at 0.05 level of significance.

Select one:

a. 2.17

b. 1.88

c. 2.73

d. 2.25

e. 3.35
