The 11 members of the swim team completed the following numbers of laps at today's practice. 76, 77, 78, 79, 80, 82, 84, 85, 86, 86, 89 Complete the parts below to identify any outliers. (a) Let Q₁ be the lower quartile and Q, be the upper quartile of the data set. Find Q, and Q, for the data set. Q₁ = 9₁=1 (b) Find the interquartile range (IQR) of the data set. IQR = Lower boundary: Upper boundary: X (c) Calculate a lower boundary using Q₁-1.5-IQR. Calculate an upper boundary using Q3 +1.5-IQR. (Note that 1.5-IQR means 1.5 times the IQR.) X Outliers: X (d) Any values less than the lower boundary or greater than the upper boundary are considered outliers. Identify the outliers of the data set. If there is more than one outlier, separate them with commas. If there are no outliers, click "None". X None S
