EqualVariances is an option to statistical confidence interval and hypothesis test functions of two samples that specifies that unknown population variances are equal.
FullReport is an option to hypothesis test functions that specifies whether all report information should be returned.
KnownVariance is an option to statistical confidence interval and hypothesis test functions that specifies the value of the population variance.
MeanDifferenceTest[list_1, list_2, \[CapitalDelta]\[Mu]_0] performs a test with null hypothesis \[Mu]_1 - \[Mu]_2 = \[CapitalDelta]\[Mu]_0.
MeanTest
(Hypothesis Testing Package Symbol) MeanTest[list, \[Mu]_0] performs a test with null hypothesis \[Mu] = \[Mu]_0.
SignificanceLevel is an option to hypothesis test functions that specifies the significance level for the test.
TwoSided
(Hypothesis Testing Package Symbol) TwoSided is an option to hypothesis test functions that specifies whether the test should be two-sided.
VarianceRatioTest[list_1, list_2, r] performs a test with null hypothesis \[Sigma]_1 2/\[Sigma]_2 2 = r.
