Question

weights of cats (in pounds)
the weights of 9 different cats, in pounds, were used to create the box plot above. which of the numbers below is the range of the set of weights?
a. 3
b. 7
c. 1.5
d. 11

Explanation:

Step1: Recall range formula

Range is calculated as \( \text{Range} = \text{Maximum value} - \text{Minimum value} \).

Step2: Identify max and min from box plot

From the box plot, the minimum value (leftmost dot) is at 8, and the maximum value (rightmost dot) is at 15? Wait no, looking at the plot: the left dot is at 8, the right dot at 15? Wait no, the x - axis: 0 - 20. Wait the left dot is at 8, the right dot at 15? Wait no, let's check again. Wait the box plot: the left whisker starts at 8, the right whisker ends at 15? Wait no, the red dots: left at 8, right at 15? Wait no, the problem says 9 cats. Wait range is max - min. Let's see the options. Wait maybe I misread. Wait the left dot is at 8, the right dot at 15? No, 15 - 8 = 7? Wait option B is 7. Wait let's re - check. The minimum value (the smallest weight) is 8, the maximum value (the largest weight) is 15? Wait 15 - 8 = 7. So range is 7.

Answer:

B. 7
