In Exercise 3.4 we saw two distributions for triathlon times: N(µ = 4313,sd = 583) for Men, Ages 30 - 34 and N(µ = 5261,sd = 807) for the Women, Ages 25 - 29 group. Times are listed in seconds. Use this information to compute each of the following:

(a) The cutoff time for the fastest 5% of athletes in the men's group, i.e. those who took the shortest 5% of time to finish.

(b) The cutoff time for the slowest 10% of athletes in the women's group.
