Explanation:
When you want to know how many scores are above a certain value, look at all score ranges that are strictly higher than that value and add up their frequencies. Scores above 79 fall in the 80–84, 85–89, and 90–94 ranges. Their frequencies are 5, 4, and 3 respectively. So the total is 5 + 4 + 3 = 12. Therefore, 12 students had scores higher than 79.
