An indoor running track is 200 meters in length. During a 3,000-meter race, runners must complete 15 laps of the track. An electronic timing device records the amount of time it takes each runner to complete a lap for every lap in the race. These are called lap times. The histograms below display the lap times for both Stefano and Alex, runners in the 3,000-meter race. Using the histograms, which of the following is a correct comparison? Neither runner had a lap time between 35 and 36 seconds. Alex’s lap times show less variability than Stefano’s lap times. The median lap time for both runners is in the 38–39 interval. Both runners’ highest number of lap times in the 37–38 interval.
