The BMW Z8, Ferrari, and Lamborghini have notably low gas mileage among the two-seater cars in the table below). Find the five-number summary (median, the quartiles (first and third quartile), and the high and low extremes) of the city gas mileages. Create a histogram with a class width of 2 (see How to Make a Histogram in Excel on Blackboard) and a boxplot of the data. Are any of these cars suspected low outliers by the Interquartile Range Rule (1.5×IQR rule)? (A point is a suspected outlier if it lies more than 1.5×IQR below the first quartile (Q1) or above the third quartile (Q3).) Recalculate and redraw any plots after checking for outliers, if needed.
