Ten athletes in the Florida Running Club ran two races of the same length. The scatter plot shows their times. Select all statements that are true. Nine of the times for the first race were at least 16 seconds. Eight of the times for the second race were less than 17 seconds. There were seven athletes who were faster in the second race than in the first. There were three athletes who had the same time in both races. There were three athletes whose times in the two races differed by exactly 1 second. What was the greatest difference for a single runner in finishing times in the races?
