Question

The data below represents the number of hours an office assistant spends on the phone every week for 15 weeks.

Answer 1

A box plot contains two dots placed at the ends of the data for the mininum and the maximum value with a line placed over the median.

Let's put the numbers in your set in order from low to high:

5

6

7

8

9

9

9

10

12

14

17

17

18

19

19
