Multiple choice question that's hard to figure out and understand.(information provided)
Ten members of a fraternity take a statistics course. Here are their scores on the first exam in the course: 61,74,47,60,62,63,65,79,55,85.
The question states: In all, 135 students too the exam. The third quartile for all 135 scores was 69. How many students had scores higher than 69? a. 34, b.67, c.69 and d.101

well, 3/4 of the scores were below 69.
That leaves 1/4 above. What's 1/4 of 135?
