Truck arrivals at a terminal follow a Poisson process with an average of 2 trucks per hour. Consider the scenario where a truck has just arrived at the terminal. An employee wants to make sure he has enough time to take a break. Let T be the waiting time (in hours) before arrival of the next truck. Determine the probability that this employee can take a 15 minute break, that is, calculate P (T> 0.25).

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
