A safety light is designed so that the times between flashes are normally distributed with a mean of 4.50 s and a standard deviation of 0.60 s.

a. Find the probability that an individual time is greater than 5.00 s.

b. Find the probabliity that the mean for 70 randomly selected times is greater than 5.00 s. c. Given that the light is intended to help people see an obstruction, which result is more relevant for assessing the safety of the light?
