The finish times for women in the 25-29 age group of the Hermosa Beach Triathlon in California are normally distributed with a mean of 5261 seconds and a standard deviation of 807 seconds. The finish times for men in the 30-34 age group of the same triathlon are normally distributed with a mean of 4313 seconds and a standard deviation of 583 seconds. a) Use the Empirical Rule to determine between what two values we expect the middle 95% of the women's 25-29 age group finish times to fall. • smaller time: (do not round your answer) • larger time: (do not round your answer)

Question
The finish times for women in the 25-29 age group of the Hermosa Beach Triathlon in California are normally
distributed with a mean of 5261 seconds and a standard deviation of 807 seconds.
The finish times for men in the 30-34 age group of the same triathlon are normally distributed with a mean of 4313
seconds and a standard deviation of 583 seconds.
a) Use the Empirical Rule to determine between what two values we expect the middle 95% of the women's 25-29
age group finish times to fall.
• smaller time:
(do not round your answer)
• larger time:
(do not round your answer)
b) The slowest 10% of women's 25-29 fınish times are greater than what time?
• z=
(round to 2 decimal places)
• finish time =
(round to 2 decimal places)
c) Adeline (female, age 24) finished the Hermosa Triathlon in 6448 seconds. Nael (male, age 31) fınished in 4854
seconds. Obviously, Nael ran faster than Adeline, but they are curious about how they did within their respective
age groups.
• What is Adeline's standardized score? z =
(round to 2 decimal places)
• What is Nael's standardized score? z =
(round to 2 decimal places)
• Who did better (had a faster time) in their age group?
(Type Adeline or Nael in the box. Be
careful to spell the name correctly.)
