Problem 6E

The random variable is the moisture content of a lot of raw material, measured to the nearest percentage point.

Answer

Step 1 of 1

(a)

We are asked to find the range of the random variable.

The random variable is the moisture content of a lot of raw material, measured to the nearest percentage point.

The function which assigns a numerical value to each outcome in the sample space, is a random variable.

The range of the random variable is the set of all possible numbers which can be assigned to the random variable.

Let represent the percent moisture content of a lot of raw material.

In this case, we could model the percent moisture content of a lot of raw material as a discrete or continuous random variable.

Hence the discrete range would be,

And the continuous range would be,
