Two athletes are training for a cycling race. Each athlete recorded the distance (in miles) of their previous 95 training rides. The box-and-whisker plots below (sometimes called boxplots) summarize the distances recorded for each athlete. Use the box-and-whisker plots to answer the questions. 5 10 15 20 25 Athlete A Athlete B + 30 35 40 45 Distance (in miles (a) Which athlete went on more rides longer than 21 miles? 'Choose one' (b) Which athlete had distances with a larger interquartile range (IQR)? 'Choose one' (c) Which athlete went on the shortest training ride? 'Choose one' (d) Which athlete had a greater median distance? 'Choose one'

4.3) •VA report from Texas Transportation Institute (Texas A&M University System 2005) on Congestion Re- duction Strategies looked into the extra travel time (due to traffic congestion) for commute travel per traveler per year in hours for different urban areas. Below are the data for urban areas that had a population of over 3 million for the year 2002. Extra Hours per Traveler per Year Urban Area Los Angeles San Francisco 98 75 Washington DC Atlanta 66 64 Houston 65 Dallas, Fort Worth Chicago Detroit 61 55 54 Miami 48 Boston 53 New York 50 Phoenix 49 Philadelphia 40 4. Compute the mean and median values for extra travel hours. Based on the values of the mean and median, is the distribution of extra travel hours likely to be approximately symmetric, positively skewed, or negatively skewed?
