To find the midrange, we need to find the average of the maximum value and the minimum value of the data set.

The minimum value is the lower class limit of the first interval, which is 70 in.

The maximum value is the upper class limit of the last interval, which is 83 in.

Therefore, the midrange is (70 + 83) / 2 = 76.5 in.

The closest choice is A) 76.6 in., which is rounded to one decimal place.
