Question

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 time it takes each runner to complete a lap for every lap in the race. these are called lap times. the histogram displays the lap times for stefano, a runner in the 3,000 - meter race. stefano’s 3,000 - meter race lap times (histogram: x - axis is lap times (seconds) with intervals 30 - 31, 32, 33, 34, 35, 36, 37, 38, 39, 40 - 41; y - axis is frequency with values 0, 2, 4, 6) which of the following is a true statement based on the histogram? option 1: there were six laps with times less than 37 seconds. option 2: the interval from 37 to 38 seconds saw the most lap times. option 3: there were three laps with times greater than 38 seconds. option 4: there were no lap times between 35 and 36 seconds.

Explanation:

1. Verificamos la primera afirmación: Sumamos las frecuencias de las vueltas con tiempo menor a 37 segundos: 1 (31s) + 1 (34s) + 1 (36s) = 3, no 6. Es falsa.
2. Verificamos la segunda afirmación: El intervalo de 37 a 38 segundos tiene la frecuencia más alta (4), lo que significa que fue el intervalo con más vueltas. Es verdadera.
3. Verificamos la tercera afirmación: Hay 1 vuelta en el intervalo de 36 segundos, así que sí hay vueltas entre 35 y 36 segundos. Es falsa.
4. Verificamos la cuarta afirmación: Sumamos las frecuencias de las vueltas con tiempo mayor a 38 segundos: 5 (39s) + 1 (40s) + 2 (41s) = 8, no 3. Es falsa.

Answer:

The interval from 37 to 38 seconds saw the most lap times.
