SignificanceLevel
is an option to hypothesis test functions that specifies the significance level for the test.
Details and Options
- To use SignificanceLevel, you first need to load the Hypothesis Testing Package using Needs["HypothesisTesting`"].
- The significance level for a test is the probability of rejecting the null hypothesis when it is in fact true.
- The value of SignificanceLevel can be any number between 0 and 1 or None. The default setting is None.
- If SignificanceLevel is a number, the output contains a statement of whether the hypothesis is accepted or rejected.
