You use hypothesis tests to test the validity of hypotheses
that relate to the statistical parameters of one or two
populations. The tests are based on statistics of samples
of the populations.
The HP 39gII hypothesis tests use the Normal
Z-distribution or Student's t-distribution to calculate
probabilities.
