To find the midpoint of a class interval, we take the average of the upper and lower class limits. For class 8 to 12, the lower limit is 8 and the upper limit is 12. So, the midpoint is (8+12)/2 = 10. Therefore, the midpoint of the yearly number of unprovoked alligator attacks falls within class 8 to 12.
