Answer:
IQR = 5
The IQR covers 50%
Step-by-step explanation:
The interquartile range is the right line of the box minus the left side of the box
UQ - LQ = IQR
8 - 3 = 5
The interquartile range is 5
Now to find the percent in the interquartile range.
The Box divides the data in quartiles or 25%
The dot to the left line is 25%
The left line to the middle is 25%
The middle to the right line is 25%
The right line to the right dote is 25%
From the left line to the right line is 25% + 25% = 50 %
The IQR covers 50%
