# VarianceRatioTest

 VarianceRatioTest[list1, list2, r]performs a test with null hypothesis 12/22=r.
• VarianceRatioTest[list1, list2, r] gives a p-value for the test that the ratio of the variances 12 and 22 of the populations from which list1 and list2 were sampled is significantly different from r.
• VarianceRatioTest is based on an F-ratio distribution with Length[list1]-1 and Length[list2]-1 degrees of freedom.
• The following options can be given:
 FullReport False whether to include detailed information about a test SignificanceLevel None significance level of the test TwoSided False whether to perform a two-sided test
• With the option , VarianceRatioTest also returns the ratio of sample variances, the test statistic, and the distribution used to generate the p-value.
