Document Summary

Stat 1000q lecture 13 - the normal distribution, continued. Function calculations on the ti-83 or ti-84 (in case the original instructions are inaccessible) The top will say mathprint; scroll to the right to classic; press. Scroll down to stat wizards; scroll right to off; press enter: press clear key, press 2nd distr, scroll down to invnorm; press. Enter: the screen will display invnorm( and wait for your input, for the value of b, use invnorm: invnorm(p, , ) If you omit and , they will default to 0 and 1. Use this calculation when: you are given a probability or area, p. 0 < p < 1: you are asked to nd the point b such that the area under a n( , ) curve to the left of b is p. Then the z-score of x has a n(0, 1) distribution. For any two points a and b with a less than b:
