D7. In track, sprinters typically use starting blocks because they think it will help them run a faster race. To test this belief, an experiment was designed where each sprinter on a track team ran a 50-meter dash two times, once using starting blocks and once with a standing start. The order of the two different types of starts was determined at random for each sprinter. The times (in seconds) for 8 different sprinters are shown in the table. Sprinter With blocks Standing start 6.12 6.38 6.42 6.52 5.98 6.09 6.80 6.72 CO V Q UT A W N 5.73 5.98 6.04 6.27 6.55 6.71 6.78 6.80 Do the data provide convincing evidence that sprinters like these run a faster race on average when using starting blocks?
