Answer 1

Answer #1

By using the minitab draw the boxplot of the given data

Boxplot of IQ From the boxplot the length of the tails are almost same on both the sides so the shape of the distribution is approximatly symmetric 140 130 the center of the distribution is median 110 120 Median 110 Here there are 4 outliers 72, 74, 77, 79 110 100 90 80 70
