At least 4

10% of 12 is 1.2

So 30% is 3.6

And 1% 0.12

So 2% is 0.24


Plus 3.6 onto 0.24 and you get 3.84

Help me please ........​
svet-max [94.6K]

The IQR is the range of the box in the box and whisker plot

So if you remember how to do the average of something you are already there

You need 2 numbers

First being the lower quartile and upper quartile

48 is where the lower quartile starts and 70 is where the upper quartile finishes *NEVER USE MEDIAN IN IQR

all you have to do is subtract

70-40 and you get as an answer 22.0 being A as your answer
