4 sqrt32 + 4 sqrt48
= 4 sqrt2* sqrt16 + 4 sqrt3 * sqrt16
= 16 sqrt2 + 16sqrt3
= 16(sqrt2 + sqrt3)
The interquartile range of this set of data is 55.
First, you need to put all 10 of the numbers in order. Then, first the first and third quartile. That is the middle of the lower half and middle of the upper half.
Those values are 23 and 78,
The IQR is the difference of those values.
78 - 23 = 55
