1. Given the following quantitative data set of size 26, answer the questions that follow: 30 30 60 63 70 79 87 90 101 102 115 118 119 119 120 125 140 145 172 182 183 191 222 244 291 511 (a) Construct an appropriate simple statistical plot(beside a dotplot) to de- scribe the data. Give comments. (b) Does this data set contain an outlier? Be detailed in your answer. Yes or No answer is not enough. UOF = Q3 +3IQR; UIF = Q3 +1.5IQR; LOF = Q1 - 3IQR; LIF = Q1 - 1.5IQR. Give comments.
