# Hypothesis Testing Using Pre-programmed Features - HP 50g User Manual

Graphing calculator.

Two-tailed test
If using a two-tailed test we will find the value of z
Pr[Z> z
where
(z) is the cumulative distribution function (CDF) of the standard normal
distribution.
Reject the null hypothesis, H
In other words, the rejection region is R = { |z
region is A = {|z
One-tailed test
If using a one-tailed test we will find the value of z
Reject the null hypothesis, H

## Hypothesis testing using pre-programmed features

The calculator provides with hypothesis testing procedures under application 5.
Hypoth. tests.. can be accessed by using ‚Ù—— @@@OK@@@.
As with the calculation of confidence intervals, discussed earlier, this program
offers the following 6 options:
