5, 7, 7, 7, 8, 10, 12, 15, 20, 22 What is the interquartile range of this data set?

Step-by-step explanation:

UQ: equation is n+1/4*3

So 10+1 is 11 11/4 is 2.75 2.75*3 is 8.25th data

UQ is 15

LQ: Equation is n+1/4

So 10+1 is 11 11/4 is 2.75th data

LQ is 7

IQR= UQ-LQ

so 15-7 is 8

IQR is 8

Hope this helps

Have a nice day:)

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
