Question 5: Suppose the traffic light at a specific intersection changes to green at 4-minute
intervals. If a car arrives at the traffic light at a random time, then X = waiting time in minutes, is
uniformly distributed between 0 and 4.
a) Find the probability that a driver waits less than 1.5 minutes.
b) Suppose a random sample of 35 cars are observed and their waiting time is recorded.
What is the probability that the sample mean of the waiting times is less than 1.5
minutes?
