Put numbers in order: 4,5,6,6,7,8,9,9,10,10,12,12,14,15
Cut the list into two equal parts: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Find middle numbers: 4,5,6,6,7,8,9 and 9,10,10,12,12,14,15
Lower quartile: 6
Upper quartile: 12
The difference of the values of the first and third quartiles of the data set is 12 - 6 = 6
X=5.2

Answer:

Step-by-step explanation:
In the equation: 
x's can be simplified and y's can be simplified!
Always remember that for exponents, you subtract the powers when dividing
so for x: 15-8 = 7
for y: 9-3 = 6
so the final answer is:
