Since the class midpoints are recorded to the nearest dollar, we can assume that each class has a width of 3 dollars (halfway between 62.50 and 65.50). Therefore, to find the class limits for the third class, we can add and subtract 1.5 from the midpoint of $67.50. This gives us the class limits of $66 and $69, which correspond to choice C.
