Hello!
You have to first find the median
74, 74, 83, 83, 83, 86, 87, 90, 92, 93, 93, 94
The numbers in the middle are 86 and 87
The average of these numbers are 86.5
The median is 86.5
This is shown in the box plot so the median is right
The lower quartile is the median of the numbers less than 86.5
74, 74, 83, 83, 83, 86
The median of these numbers is 83
The lower quartile is right
The find the upper quartile you find the average of the numbers higher than 86.5
87, 90, 92, 93, 93, 94
The upper quartile is 92.5
Since this is shown differently in the box plot the answer is upper quartile
The answer is C) upper quartile
Hope this helps!
Answer: 500, or actually, somewhere between 450 and 550.
Step-by-step explanation:
5/7 × 700 = 500
This isn't actually true unless someone actually counted the students. And if they did, the result wouldn't have been such a round number, so 5/7 is rounded
A better answer would be to interpret 5/7 as 4.5/7 to 5.5/7, or 450 to 550.
