To solve this problem you must apply the proccedure shown below:
1- By definition, the formula for calculate the i<span>nterquartile range is
I</span><span>nterquartile range=Q3-Q1
Where Q1 is the lower quartile and Q3 is the upper quartile.
2-Keeping this on mind, you have:
</span>Interquartile range=Q3-Q1
<span>
Q3=245
Q1=201
</span>Interquartile range=245-201
Interquartile range=44
<span>
Therefore, the answer is: 44

Step-by-step explanation:
The constant -h is half the x-coefficient -4, so is -2. That makes h = 2.
The square of the binomial (x-h) is ...
... (x -h)² = x² -2hx +h²
Comparing x-terms, you see that ...
... -2xh ≡ -4x
... h = (-4x)/(-2x) = 2
