The 11 members of the swim team completed the following numbers of laps at today's practice. 29, 77, 77, 78, 80, 83, 84, 88, 90, 91, 156 Complete the parts below to identify any outliers. (a) Let O, be the lower quartile and Q, be the upper quartile of the data set. Find Q, and Q, for the data set. 91 = 0 X (b) Find the interquartile range (IQR) of the data set. IQR = X (c) Calculate a lower boundary using Q, - 1.5.IQR. Calculate an upper boundary using O, + 1.5 .IQR. (Note that 1.5 .IQR means 1.5 times the IQR.) Lower boundary: X Upper boundary
