the ages of 8 different students in a college math class were used to make the box plot shown above. which of the following numbers below is the range of the ages?
a. 18
b. 3
c. 8
d. 5

Explanation:

Step1: Recall the formula for range

The range of a data set is calculated as the difference between the maximum value and the minimum value, i.e., \( \text{Range} = \text{Maximum} - \text{Minimum} \).

Step2: Identify maximum and minimum from the box plot

From the box plot, the minimum age (leftmost dot) is at 20, and the maximum age (rightmost dot) is at 28.

Step3: Calculate the range

Using the formula, \( \text{Range} = 28 - 20 = 8 \).

Answer:

C. 8
