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
Victor or Junior, did you multiply my response to find the answer?
To find the number of students who had scores higher than 69, we need to count the number of scores in the data set that are greater than 69.
First, let's arrange the scores in ascending order: 47, 55, 60, 61, 62, 63, 65, 74, 79, 85.
Since there are 10 students in the fraternity, we can ignore any scores below 61 because the first seven scores are below the members' scores.
Now, we need to count the number of scores higher than 69. From the arranged scores, we can see that there are four scores greater than 69: 74, 79, and 85.
Therefore, there are 4 students who scored higher than 69.
