a) The number of beaches in each class is represented by the height of the class. The class that has the least frequency is the one with 5-7.

We can see that the height is 2, thus the number of beaches in this class is 2.

b) We can see that each class has width 3:

2 to 4: 2, 3, 4

5 to 7: 5, 6, 7

and so on

The width of each class is 3.

c) The classes with 11 or more are the last two, from 11 to 13 and from 14 to 16.

The height of the class 11 to 13 is 4

The height of the class 14 to 16 is 7

The total beaches with 11 or more pregnant turtles is the sum: 4 + 7 = 11
