Look for the line plot that meets all three requirements:
- the tallest stack (the peak) is at 1.75 hours,
- the range (max − min) is 2.25 hours,
- there are 15 total data points (dots).
So the correct plot is the one whose smallest value is 0.50 and largest value is 2.75 (2.75 − 0.50 = 2.25), with the most dots stacked at 1.75, and a total of 15 X's.
