Answer:
75%
Step-by-step explanation:
The edges of a box in a box plot represent the first quartile and the third quartile.
A quartile is 25% of the data. This makes the first quartile 25%, and the third quartile 75%. The indicated range, from 27 to 45, goes from the lowest point to the 75% mark; this means it contains about 75% of the data.
