Geo stats question:

2)Drivers wishing to turn left at a particular intersection arrive at an average rate of five per minute. (i) if the left-turn arrow is red for 30 seconds, and there is room in the left-turn lane for five cars, what is the probability that the capacity of the lane will be exceeded for a given cycle of the signal? (ii) Given that transportation planners and traffic engineers wish to reduce the probability to less then 0.05 by shortening the length of the red signal, how would you determine the maximal time the signal could remain red?

A left turn lane is to be designed at a signalized intersection to accommodate leftturning vehicles during the peak period of traffic. If the design peak hour volume for the left turn movement is 150 vehicles per hour and the red time interval per signal cycle for the left turn movement is 60 seconds. a) Compute the average number of left turn vehicle arrivals per red interval of each signal cycle during the design peak hour. b) Assume that left...

Vehicles entering an intersection from the east are equally likely to turn left, turn right, or proceed straight ahead.

Vehicles entering an intersection from the east are equally likely to turn left, turn right, or proceed straight ahead. If 70 vehicles enter this intersection from the east, use technology and the normal approximation to the binomial distribution to find the exact and approximate probabilities of the following. (Round your answers to four decimal places.) (a) 26 or fewer turn right exact probability = approximate probability = (b) at least two-thirds of those in the sample turn exact probability...

Suppose that vehicles taking a particular freeway exit can turn right (R), turn left (L), or go straight (S). Consider observing the direction for each of three successive vehicles. (Enter your answers in set notation. Enter EMPTY or ∅ for the empty set.) (a) List all outcomes in the event A that all three vehicles go in the same direction. A = (b) List all outcomes in the event B that all three vehicles take different directions. B = ...

A) Phone calls arrive at a particular call center with an average of 12 every minute. The call center management want the maximum probability of having more calls than staff in any given minute being .2. How many staff are necessary to ensure this? Use Excel to help you find the answer. B) Consider the 1981 Super Bowl commercial from Schlitz involving a live taste test. Schlitz sponsored a live taste test for its beer during the half time of...

3. A particular Intersession stats prof is noted for 2 things: the number of pages of notes his students have to write down each night and the number of pieces of chalk he destroys each night. To see if there is any relationship between these, a record is kept of the number of pages of notes his students write during 6 different lectures in June and the number of pieces of chalk the prof destroys on these nights. The following...

2. The average time it takes to take a stats test is 1.13 hours. I wish to test to see if the last 8 exams had a time that was different from normal. The average time to do the 8 exams was 1.2 hours with a standard deviation of .4 hours. a) At the .05 level did the last exams take times that were of different length (p = .64) b) Interpret the p-value c) Find and interpret the 95%...

Customers arrive at a local grocery store at an average rate of 2 per minute. (a) What is the chance that no customer will arrive at the store during a given two minute period? (b) Since it is a “Double Coupon” day at the store, approximately 70% of the customers coming to the store carry coupons. What is the probability that during a given two-minute period there are exactly four (4) customers with coupons and one (1) without coupons? (c)...

Customers arrive at a cafe every 2 minutes on average according to a Poisson process. There are 2 employees working at the bar providing customer service, i.e., one handling customer orders and another handling payments. It takes an average of 1 minute to complete each order (exponentially distributed). Based on the above: f. What are the service time probability density and cumulative distribution functions? g. What percentage of customer orders will be prepared in exactly 2 minutes? h. What are...

Question B2 (30 pts): Customers arrive to Lincoln Savings Bank (LSB) with an average rate of 3 customers per minute. The average time a teller takes to serve a customer is 5 minutes. Standard deviation of customer inter-arrival time is 1.5 minutes and standard deviation of service time is 3 minutes. LSB employs 20 tellers. All customers form a single waiting line and can be served by any of the tellers in a first-come-first-serve basis as tellers become available. For...
