MeanTest

MeanTest[list,μ0]

performs a test with null hypothesis μ=μ0.

Details and Options

  • To use MeanTest, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
  • MeanTest[list,μ0] gives a ‐value for the test that the mean of the population from which list was sampled is significantly different from μ0.
  • If the variance is assumed known, MeanTest is based on the normal distribution.
  • If the variance is not assumed known, MeanTest is based on Student's distribution with Length[list]-1 degrees of freedom.
  • The following options can be given:
  • FullReport Falsewhether to include detailed information about a test
    KnownVariance Nonevariance of population
    SignificanceLevel Nonesignificance level of the test
    TwoSided Falsewhether to perform a two-sided test
  • With FullReport->True, MeanTest also returns the sample mean, the test statistic, and the distribution used to generate the -value.
