Answer:
A number line goes from 0 to 16. The whiskers range from 1 to 12, and the box ranges from 5 to 8. A line divides the box at 7.
Step-by-step explanation:
The data set is 1, 1, 5, 5, 7, 8, 8, 10, 12.
The number in the very middle is 7, or the median. The line should divide the box at 7.
Since the least number is 1 and the most is 12, the whiskers range from 1- 12. This represents our range.
For the box, you have to find the median of the two separate boxes the line divides it into. In other words, you have to find the median of the data sets 1, 1, 5, 5, 7 and 7, 8, 8, 10, 12. These "medians" are 5 and 8. This represents the interquartile range.
Therefore, the answer is "A number line goes from 0 to 16. The whiskers range from 1 to 12, and the box ranges from 5 to 8. A line divides the box at 7."
