Answer:
D
Step-by-step explanation:
Put the numbers in order:
16, 16, 16, 17, 18, 19, 19, 20, 23
18 should be the middle of the box and whisker plot. The whisker on the left should be at 16(smallest) and the whisker on the right should be at 23(largest). Answer D is the only one that fits this data.
