Normal Distribution Problems with Solutions. 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.
A normal distribution, sometimes called the bell curve, is a distribution that occurs naturally in many situations.For example, the bell curve is seen in tests like the SAT and GRE. The bulk of students will score the average (C), while smaller numbers of students will score a B or D.
This video shows how to calculate probabilities for word problems using the normal distribution. Skip navigation ... Finding Probability of a Sampling Distribution of Means Example 1 ...
Find here some normal distribution word problems or some applications of the normal distribution. Example #1. Suppose the current annual salary of all teachers in the United States have a normal distribution with a mean of 51000 dollars and a standard deviation of 6000 dollars.
μ is another fancy code name for the mean of the normal distribution, while σ is its standard deviation. We can find the Z-scores for 6 and 9 inches now. How much of the normal distribution falls within 1 standard deviation above or below the mean? According to the Empirical Rule, that's 68% of the distribution. Problem solved, no table needed.

The standard normal distribution, which is more commonly known as the bell curve, shows up in a variety of places. Several different sources of data are normally distributed. As a result of this fact, our knowledge about the standard normal distribution can be used in a number of applications.
