Answer:
75%
Explanation:
Box and whisker plots divide data into four sections, or quartiles.
The bar in the center of the box is the median of all the data. (In this case, that's 27.) The box represents the middle 50% of the data, and the whiskers represent the remaining two quartiles. So, since the box and one of the whiskers are above 23, 3 of the 4 quartiles of the data are above 23. That's 75%
