# Find the Mean and Range of 18, 23, 10, 39, 22, 17, 16, 15.

We will be using the formulas of mean and range to solve this.

## Answer: The mean is 20, and the range is 29.

Let's solve it step by step.

**Explanation:**

Given that 18, 23, 10, 39, 22, 17, 16, 15.

The formula for mean is:

Mean = Sum of terms / No. of terms

The total number of observations = 8.

Mean = 1/8 (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)

Mean = 160 / 8

Mean = 20

The range is given by:

R = X(max) - X(min)

X(max) = 39, X(min) = 10.

R = 39 - 10

R = 29
