**Finding Expected Value, Variance, and Standard Deviation** In Exercises 1-12, use the given probability density function over the indicated interval to find the (a) expected value,

(b) variance using the alternative formula, and

(c) standard deviation of the random variable.

(d) Then sketch the graph of the probability density function and locate the mean on the graph. See *Examples 1, 2, and 5.*

**(a)**

To determine

**To calculate:** The expected value for the probability density function,

Explanation

**Given Information:**

The provided probability density function is

**Formula used:**

The expected value for the continuous random variable, *x* with density function

**Calculation:**

Consider the provided probability density function,

So,

Substitute the values

**(b)**

To determine

**To calculate:** The variance for the probability density function,

**(c)**

To determine

**To calculate:** The standard deviation for the probability density function,

**(d)**

To determine

**To graph:** The probability density function,
