Normal distribution problems with answers. Problems and applications on normal distributions are presented. The solutions to these problems are at the bottom of the page. Also an online normal distribution probability calculator may be useful to check your answers.


But we do not need to work with a different normal distribution for every application. Instead, we work with a normal distribution with a mean of 0 and a standard deviation of 1. We will look at a few applications of this distribution that are all tied to one particular problem.


Normal Probabilities Practice Problems Solution Courtney Sykes Normal Probabilites Practice Solution.doc 5. The average number of acres burned by forest and range fires in a large New Mexico county is 4,300 acres per year, with a standard deviation of 750 acres. The distribution of the number of acres burned is normal.


TI-89 Graphing a Normal Distribution Curve. The TI-89 can not only calculate z-scores and return values for normal distributions, it can graph the normal distribution curve as well. Graphing a normal distribution can help you see what it is you are supposed to be looking for, and gives you one more tool in solving normal distribution problems.

Solving Problems Involving Using Normal Distribution . Problem 1: Suppose that the data concerning the first-year salaries of Baruch graduates is normally distributed with the population mean µ = $60000 and the population standard deviation σ = $15000. Find the probability of a randomly selected Baruch graduate earning less than $45000 annually.
