To find the cumulative percentage below the lower real limit of the interval 90-99, we need to add up the cumulative percentage of all intervals below 90-99. We can see from the table that the cumulative percentage for the interval 80-89 is 78.88% and the cumulative percentage for the interval 70-79 is 96.68%. Therefore, the cumulative percentage below the lower real limit of the interval 90-99 is 78.88% + 96.68% = 98.56%. Therefore, the correct answer is D) 98.56.
