3.6 Triathlon times, Part II: The distribution for triathlon time varies depending on the population you are describing. The distribution for men ages 30 - 34 is N(µ=4337, o-593). The distribution for women ages 25 - 29 is N(H=5287, o=834). Note, these distributions list the triathlon times in seconds. Use this information to compute each of the following. Round all your answers to 2 decimal places. a) The cutoff time for the fastest 5.5% of athletes in the men's group, i.e. those who took the shortest 5.5% of time to finish. b) The cutoff time for the slowest 10% of athletes in the women's group.
