Question
A phone company report on the number of texts sent each day included these displays.
A box-and-whisker plot. The number line goes from 50 to 95. The whiskers range from 55 to 70, and the box ranges from 57 to 64. A line divides the box at 62. A second box-and-whisker plot. The number line goes from 50 to 95. The whiskers range from 63 to 93, and the box ranges from 71 to 85. A line divides the box at 78.
For each statement, select the answer that correctly compares the two plots.
A typical 8- to 12-year-old texts
times per day.
A typical 13- to 17-year-old texts
a typical 8- to 12-year-old.

To compare the two box-and-whisker plots based on the information provided:
1. **A typical 8- to 12-year-old texts:**
- The first box-and-whisker plot (representing 8- to 12-year-olds) has a median (line dividing the box) at 62 texts per day.
2. **A typical 13- to 17-year-old texts:**
- The second box-and-whisker plot (representing 13- to 17-year-olds) has a median at 78 texts per day.
Based on these interpretations:
- A typical 8- to 12-year-old texts **62** times per day.
- A typical 13- to 17-year-old texts **78** times per day, which is greater than 62.
Thus, the completed statements would be:
- A typical 8- to 12-year-old texts **62** times per day.
- A typical 13- to 17-year-old texts **more than** a typical 8- to 12-year-old.
In summary:
- 8- to 12-year-olds average 62 texts.
- 13- to 17-year-olds average 78 texts, indicating they text more than the younger age group.
