Homework Answers
probability of at least 2 vehicles being found within the interval for a randomly selected 5-minute interval =P(X>=2) =1-P(X<=1)
=1-P(X=0)-P(X=1) =1-e-3-e-3*31/1! =1-4e-3
option C is correct

1. At a specified point on a highway, vehicles are known to arrive according to a Poisson distribution. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals. It is noted that no cars arrive in 18 of these 120 intervals. Determine the number of these 120 intervals in which exactly three cars arrive. 2. For the data collected in previous problem, estimate the percentage of time headways that will be 10 seconds...

Recently a study was performed on a Queenslad highway regarding the quantity and speed of vehicles that use the road. It is your job to determine the probability of certain events with the use of probability distributions. For each question, clearly state which probability distribution the random variable follows. You must solve each problem by hand and verify using a MATLAB function. During the testing time, it was found that cars pass by at an average rate of 300 per...

The number of automobiles entering a tunnel per 2-minute period follows a Poisson distribution. The mean number of automobiles entering a tunnel per 2-minute period is four. (A) Find the probability that the number of automobiles entering the tunnel during a 2minute period exceeds one. (B) Assume that the tunnel is observed during four 2-minute intervals, thus giving 4 independent observations, X1, X2, X3, X4, on a Poisson random variable. Find the probability that the number of automobiles entering the...

On a highway, cars pass according to a Poisson process with rate 5 per minute. Trucks pass according to a Poisson process with rate 3 per minute. The two processes are independent. Let Nc(t) and NT(t) denote the number of cars and trucks that pass in t minutes, respectively. Then N(1)=NC(1)+NT(1) is the number of vehicles that pass in minutes. Find P(NT(3)-71N(3)-20)· f) Find E(N(4)INT(3)-7). Hint: NT(4)={NT(4)-NT(3)}+NT(3).

The number of major faults on a randomly chosen 1 km stretch of highway has a Poisson distribution with mean 1.4. The random variable X is the distance (in km) between two successive major faults on the highway. What is the probability you must travel more than 3 km before encountering the next four major faults? Give your answer to 3 decimal places.
