Relative Performances in Track Events In Saturday's track meet, Ryan Flahive, a high jumper, jumped 6 feet 3 inches. Conference high jump marks for the past season had a mean of 6 feet even and a standard deviation of 3.5 inches. Michael Drago, Ryan's team-mate, achieved 18 feet 4 inches in the long jump. In that event, the conference season average (mean) and standard deviation were 16 feet 6 inches and 1 foot 10 inches, respectively. Relative to this past season in this conference, which athlete had a better performance on Saturday?
