Answer:
Q1 = 40
Step-by-step explanation:
Set up numbers from least to greatest
21, 40, 52, 58, 72, 75, 96
First, find the median,
Median is: 58
Now Q1 is all numbers before the median (without counting the median)
21, 40, 52
The median here is 40
D/40
The answer is D because if you were to put them in the correct order it would be
Q1 Q2 Q3
Q1 is quartile 1 so the answer is 40
Hope this helps!
