(a) Let Q, be the lower quartile and Q, be the upper quartile of the data set. Find Q, and Q, for the data set. = 77 Q Q = 88 (b) Find the interquartile range (IQR) of the data set. X G IQR 11 = x (c) Calculate a lower boundary using Q, -1.5 IQR. Calculate an upper boundary using Q, +1.5 IQR. (Note that 1.5-IQR means 1.5 times Lower boundary: 62 Upper boundary: 103 G
