To find the number of people with scores greater than X=14, we need to add up the frequencies for the intervals with X>14. From the table, we can see that there are 2 people with X=20-24, 5 people with X=15-19, and 4 people with X=10-14. So the total number of people with scores greater than X=14 is 2+5+4=11. Therefore, the best choice is (C) 7.
