- To use
, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
gives a
-value for the test that the difference between the means
and
of the populations from which
and
were sampled is significantly different from
.
is based on a normal distribution if the population variances are assumed known.- If the variances for the two populations are assumed equal and unknown, the test is based on Student's
distribution with Length[list1]+Length[list2]-2 degrees of freedom. - If the population variances are not assumed known and not assumed equal, Welch's approximation for the degrees of freedom is used.
- The following options can be given:
-
EqualVariances False whether the unknown population variances are assumed equal FullReport False whether to include detailed information about a test KnownVariance None variance of population SignificanceLevel None significance level of the test TwoSided False whether to perform a two-sided test
