Answer:
There are 9 people in the class.
Step-by-step explanation:
Sean received the 5th highest grade in his class meaning that there are 4 people in front of him who got a higher grade. This also means that Sean has 4 people behind him who have lower grades. So,
4+4+1 (Sean himself) = 9 people
The number of students in the class is given by the sum of the frequency
of each score.
- There are at least 9 students in the class.
Reasons:
When the class scores are arranged in increasing order, we have;
Sean's position = 5 th = The fifth lowest score
Therefore;
- The number of scores lower than Sean's score = 4
When the scores are arranged in decreasing order, we have;
Sean's position = 5 th = Fifth highest score
Therefore;
- The number of scores higher than Sean's score = 4
- The total number of different scores in the class = 4 + 1 + 4 = 9
Given that two or more students can have the same score, the frequency
of each score, determines the number of students in the class, we have;
- The number of students in the class, n ≥ 9
