90, 77, 79, 60, 87, 87, 80, 80, 83

### Example 4

The box and whisker plot below was drawn using a list of numbers (data). Determine if each statement is definitely true, definitely false, or cannot be determined. If you believe it cannot be determined, cross your arms and pout, to give the impression that you are truly outraged at the lack of information.

- Half the data falls between 1 and 3.
- The number 5 must be in the list of numbers from which this plot was drawn.
- The number 1.5 must be in the list of numbers from which this plot was drawn.
