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. 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?
