Answer 2

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%
