4. "Time headway" In highway traffic flow the elapsed time between the time that one car finishes passing a fixed point and the instant that the next car begins to pass that point is called time headway. Now, let X = the time headway for two randomly chosen consecutive cars on a highway during a period of heavy traffic flow. The following probability density function of X is suggested by traffic experts: f(x) = 0.15*e-0.15*(x-0.5) for (x ≥ 0.5 sec) 0 otherwise a. Draw f(x) from x = 0 to x= 10 sec. b. Find P(X ≤ 5 sec) and show it on the figure you have drawn. c. What is E[X] and Var[X] ? d. Find Cumulative Distribution Function of X.

![4. "Time headway" In highway traffic flow the elapsed time between the time that one car
finishes passing a fixed point and the instant that the next car begins to pass that point
is called time headway.
Now, let X = the time headway for two randomly chosen consecutive cars on a
highway during a period of heavy traffic flow. The following probability density function
of X is suggested by traffic experts:
