(1 point) Triathlon times. In triathlons, it is common for racers to be placed into age and gender groups. Friends Leo and Mary both completed the Hermosa Beach Triathlon, where Leo competed in the Men, Ages 30 - 34 group while Mary competed in the Women, Ages 25 - 29 group. Leo completed the race in 4767 seconds, while Mary completed the race in 5733 seconds. Obviously Leo finished faster, but they are curious about how they did within their respective groups. Can you help them? Round all calculated answers to four decimal places. Here is some information on the performance of their groups: The finishing times of the Men, Ages 30 - 34 group has a mean of 4328 seconds with a standard deviation of 581 seconds. The finishing times of the Women, Ages 25 - 29 group has a mean of 5293 seconds with a standard deviation of 775 seconds. The distributions of finishing times for both groups are approximately Normal. Remember: a better performance corresponds to a faster finish. 1. Write the short-hand for these two normal distributions. The Men, Ages 30 - 34 group has a distribution of N( 4328 581 The Women, Ages 25 - 29 group has a distribution of N( 5293 775 2. What is the Z score for Leo's finishing time? z = .7554 3. What is the Z score for Mary's finishing time? z = .5677 4. Did Leo or Mary rank better in their respective groups? OA. Leo ranked better B. Mary ranked better C. They ranked the same 5. What percent of the triathletes did Leo finish slower than in his group? 77.72 %. 6. What percent of the triathletes did Mary finish faster than in her group? 56.77 %. 7. What is the cutoff time for the fastest 29% of athletes in the men's group, i.e. those who took the shortest 29% of time to finish? 4007.635 seconds 8. What is the cutoff time for the slowest 28% of athletes in the women's group? 5692.471 seconds (1 point) Triathlon times.
