MeanTest[list,μ0]

performs a test with null hypothesis μ=μ0.

# Details

• 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 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
• With , MeanTest also returns the sample mean, the test statistic, and the distribution used to generate the -value.
