Question
The women’s heptathlon in the Olympics consists of seven track and field events: the 200-m and 800-m runs, 100-m high hurdles, shot put, javelin, high jump, and long jump. In the 2000 Olympics, the best 800-m time, run by Gertrud Bacher of Italy, was 8 seconds faster than the mean. The winning long jump by the Russian Yelena Prokhorova was 60 centimeters longer than the mean. Bacher’s winning 800-m time of 129 seconds was 8 seconds faster than the mean qualifying time of 137 seconds (the standard deviation of the qualifying times was 5 seconds). Prokhorova’s winning long jump was 60cm longer than the average 6-m jump (note that the standard deviation of the long jumps was 30 cm). Which performance is more outstanding (and hence deserves more points when computing their overall score)? Explain.
Explanation / Answer

8/5=1.6
The winning long jump by the Russian Yelena Prokhorova was 60 centimeters longer than the mean.
Z=60/30=2
Bacher’s winning 800-m time of 129 seconds was 8 seconds faster than the mean qualifying time of 137 seconds (the standard deviation of the qualifying times was 5 seconds).
Z= 8/5 = 1.6
Prokhorova’s winning long jump was 60cm longer than the average 6-m jump (note that the standard deviation of the long jumps was 30 cm).
Z=60/30=2
Which performance is more outstanding (and hence deserves more points when computing their overall score)? Explain.
Z score of runners are 1.6 and the long jumpers are 2 which is higher.
The long jumpers are outstanding.
