**chi-square Using Your TI-83/84 Calculator for Hypothesis**

The most basic statistical test to generate p-values with is a t-test. You can access the t-test function on a TI-83 calculator by pressing the STAT button, and then pushing the RIGHT ARROW button twice to open the TESTS list. Once there, press the number 2 or push the DOWN ARROW once to highlight "2: T-Test..." and press the ENTER button.... Calculator Instructions for Statistics Using the TI-83, TI-83 plus, or TI-84 I.

The observed sample mean produced a t statistic test statistic of -0.894. We use the t Distribution Calculator to find P(t -0.894) = 0.19. This means we would expect to find a sample mean of 108 or smaller in 19 percent of our samples, if the true population IQ were 110....The TI-83 Plus and TI-84 Plus give an option to show the sample test statistic on the normal distribution. Highlight the Draw option on the Z-Test screen. Because the sample z is so far to the right, it â€¦

By hand (although we'll still use the TI-83 to get the Z critical value) With the TI-83 Z-Test function Z-test for the proportion. By hand, but using the TI-83 to get the Z critical value With the TI-83 1-PropZTest function t-test for the mean (with summary statistics given) By hand (and using the TI-83
