Suppose the waiting time, in minutes, at a checkout line in a local super market follows a Uniform distribution in the interval (1,6) a. How long is a randomly chosen customer at the super market expected to wait at the checkout counter? b. What is the probability that a randomly chosen customer at the super market will wait between 2 and 5 minutes to be checked out? c. Suppose a random sample of 100 customers is taken at the super...

Suppose that the amount of service(ordering a coffee and getting it done) time at a KU driving- through coffee shop is exponentially distributed with an expected value of 10 minutes. You arrive at the driving-through line while one customer is being served and one other customer is waiting in the line. The staff of the coffee shop informs you that the customer has already ordered a Cafe Latte and waited for 5 minutes. What is the probability that the customer...

Do you dislike waiting in line? A supermarket chain used computer simulation and information technology to reduce the average waiting time for customers at 2,300 stores. Using a new system, which allows the supermarket to better predict when shoppers wil be checking out, the company was able to decrease average customer waiting time to just 19 seconds. (a) Assume that supermarket waiting times are exponentially distributed. Show the probability density function of waiting time at the supermarket. -(히X. elsewhere 19...

AMY HAYDEN Question 10 of 13, Step 1 of 1 9/13 Correct The time spent waiting in the line is approximately normally distributed. The mean waiting time is 6 minutes and the variance of the waiting time is 9. Find the probability that a person will wait for more than 9 minutes. Round your answer to four decimal places Answer Tables Keypad If you would like to look up the value in a table, select the table you want to...

(1 point) Once checked in at the ticket kiosk, the amount of time it takes a airline passenger at the Calgary International Airport to clear security is a random variable that can be modeled by the Exponential distribution with a = 35.1 minutes. A statistician is randomly select n = 40 airline passengers and record how long, in minutes, it takes each to clear security once each has checked in at the ticket kiosk. (a) Complete the statement below. Enter...

Problem #3: Suppose that the waiting time X (in seconds) for the pedestrian signal at a particular street crossing is a random variable with the following pdf. S (1 – x/76)8 0 < x < 76 otherwise If you use this crossing every day for the next 6 days, what is the probability that you will wait for at least 10 seconds on exactly 2 of those days? Problem #3: Round your answer to 4 decimals.

Can you solve 12
Thus, the expected time waiting is 5/6 hours (or 50 minutes) (Note that it is wrong to reason like this: Alice expects to arrive at 12:30, Bob expects to arrive at 1:00: thus, we expeet that Bob will wait 30 mimutes for Alice.) (b). We want to compute the probability that Bob has to wait for Alice, which is P(Y < X), which we do by integrating the joint density, f(r,y), over the region where <...

Many small restaurants in Portland, Oregon, and other cities across the United States do not take reservations. Owners say that with smaller capacity, no-shows are costly, and they would rather have their staff focused on customer service rather than...
