3. The data shown in the box plots shows the speed of a roller coaster based on different construction materials (steel or wood). Compare the two box-and-whisker plots: Speed of Roller Coasters by Construction (Wood or Steel) Speed 2001 150 100 50 Steel Wood Construction a. Which construction material has a higher average speed? How can you tell? b. Which construction material has more consistency in speed? How can you tell? c. Are there any outliers in the data for steel roller coasters? If so, estimate them. d. What percent of wood roller coasters are faster than 100 mph? e. Consider steel roller coasters: 75% of steel roller coasters are faster than what speed
