Hypothesis tests
You use hypothesis tests to test the validity of hypotheses about the statistical parameters of one or two
populations. The tests are based on statistics of samples of the populations.
The HP Prime hypothesis tests use the Normal Z-distribution or the Student’s t-distribution to calculate
probabilities. If you wish to use other distributions, please use the Home view and the distributions found
within the Probability category of the Math menu.
