To study the characteristics of sea stars in a group of tide pools, researchers measured the diameter of the sea stars within the tide pools. The dot plot gives the diameter, to the nearest inch, of each of the sea stars in these tide pools.

Diameter (inches)1617181920
  • The data for the dot plot are as follows:
    • 16: 6 dots
    • 17: 4 dots
    • 18: 1 dot
    • 19: 2 dots
    • 20: 3 dots

Based on the dot plot, how many sea stars had a diameter, to the nearest inch, of 16 inches?
