The following information is available for two samples selected from independent but very right-skewed populations.

Population A n1 = 25 s1^2 = 49.3 
Population B: n2 = 10 s2^2 = 38.9

Should you use the F test to test the null hypothesis of equality of variances? Discuss.

A. No. Since the variances are clearly not equal, the F test should not be used. 
B. No. Since the populations are not normal, the F test should not be used.
C. Yes. Although the populations are not normal, the F test should be used because the populations are independent. 
D. Yes. Since the populations are both right-skewed, the F test should be used.
