**Using Technology** In Exercises 17-22, use a symbolic integration utility to find the mean, variance, and standard deviation of the probability density function. Then find the percent of the distribution that lies within the given standard deviations of the mean. See *Example 3.*

Function |
StandardDeviations |

To determine

**To calculate:** The mean, variance and standard deviation of the probability density function

Explanation

**Given Information:**

The probability distribution function is,

**Formula used:**

The definition of mean over the interval

Where, *f* is a probability density function and *x* is a continuous random variable.

The definition of variance is,

The definition of standard deviation is

**Calculation:**

Consider the probability distribution function,

The mean of the function is defined as,

By the use of symbolic integration utility to find the value of mean.
