Question

life span of cats (in years)
the life spans of 8 different cats were used to create the box plot shown above. which of the numbers below is the range of the set of life spans?
a. 9
b. 3.5
c. 5
d. 7

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 (Life Span of Cats), the minimum value (leftmost dot) is at 8, and the maximum value (rightmost dot) is at 17.

Step3: Calculate the range

Using the formula, \( \text{Range} = 17 - 8 = 9 \).

Answer:

A. 9
