I did the test. The answer is "Group X has less variability in the data."
Answer:
t = 4
Step-by-step explanation:
Substitute the variables with the information provided.
205 = 100 + 12(6) + 5(t) + 7(4) + 5(5) - 8(5)
Simplify
205 = 100 + 72 + 5t + 28 + 25 - 40
20 = 5t
t = 4
In order from top to bottom, your answer should be:
A
C
B
The lower quartile is 24 and the range is 35-22=13.....hope this helps
