13. Designing Strobe Lights An aircraft strobe light is designed so that the times between flashes are normally distributed with a mean of 3.00 s and a standard deviation of 0.40 s.

a. Find the probability that an individual time is greater than 4.00 s.

b. Find the probability that the mean for 60 randomly selected times is greater than 4.00 s.
