The following are test scores on the first exam given to 30 students taking an elementary statistic course: 75, 47, 84, 63, 70, 79, 83, 93, 85, 52, 85, 84, 67, 84, 72, 58, 87, 62, 88, 77, 80, 75, 73, 71, 92, 69, 91, 98, 76, 92. We will view test score as a continuous variable. A relative frequency histogram of these data was constructed using 6 intervals each of length 8.5 with the left most interval having midpoint 47 beginning at 42.25. Using this histogram, an estimate of the proportion of the students in the population whose test scores fall between 84.75 (inclusive) and 93.25 (exclusive) is ____- 2/30 3/30 5/30 8/30
