GIven: Data sets X and Y each consist of 4 values, as shown in the table.
Asked: If the range of data set X is 21, what is the range of data set Y?
Let us suppose x1, y1 are lowest values and x4, y4 are highest values.
Range of data set X = (x4 -x1) = 21
Range of data set Y = (5x4 + 16) - (5x1+16) = 5(x4-x1) = 5*21 = 105
IMO E
