In this problem, it is said that each of 20 students in a class took a test received a whole number score.
00:05
The median of the scores was 87.
00:07
None of the students received a score of 87.
00:10
30 % of the students receive scores of 90 or above.
00:13
We need to determine how many students receive scores of 88 or 89.
00:17
So consider the scores 87, 88, 89, and 90 and above.
00:26
Now, note that the median of the scores was 87, so that means.
00:30
Means that a total of 50 % of the students scored more than 87.
00:36
And none of the students received a score of 87.
00:39
So we have 50 % of the students who scored from 88 to above 90.
00:45
And it is said the 30 % of the students receive scores of 90 or above...
