The amount of time that a customer spends waiting at an airport check-in counter is a random variable with mean 8.2 minutes and standard deviation 1.5 minutes. Suppose that a random sample of n-49 independent customers is observed. Find the approximate probability that the average time waiting in line for these customers is (a) Greater than 10 minutes (b) Between 6 and 10 minutes (c) Less than 6 minutes
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...
Q3. A customer spending waiting time at Alahwal_Jeddah check-in counter is a random variable with mean 8.2 minutes and standard deviation 1.5 minutes. Suppose that a random sample of n = 49 customers is observed. Find the probability that the average time waiting in line for these customers is: (a) Less than 9.3 minutes (b) Between 5 and 10 minutes (c) Less than 7.5 minutes
The waiting times on hold for a call to a customer service department are observed to have the following probability distribution Number of calls, x Waiting time, minutes, f(x) 3 10 15 10 6 2 4 10 The expected value of the waiting time for a random call is most nearly: 7.3 minutes 9.2 minutes 11.5 minutes 15.0 minutes
(1 point) After 8:00pm on any Thursday, the amount of time a person spends waiting in line to get into a well- known pub is a random variable represented by X. Suppose we can model the behavior of X with the Exponential probability distribution with a mean of waiting time of 45 minutes. (a) Provide the value of the standard deviation of this distribution. Enter your answer to two decimals. ox= 45 II minutes (b) Suppose you are in line...
A critically important aspect of customer service in a supermarket is the waiting time at the checkout (defined as the time the customer enters the line until he or she is served). Data were collected during time periods in which a constant number of checkout counters were open. The total number of customers in the store and the waiting time (in minutes) were recorded. . Determine the coefficient of determination, r 2 , and interpret its meaning. 6. How useful...
Trader Joe’s has one register open with the customer service employee able to process one customer every 4.8 minutes. There are approximately 2 customers checking out per hour (i.e., arrival rate during off-peak hour). What is the utilization of the customer service employee ? What is the average number of customers in the waiting line? What is the average customer waiting time in line (in minutes)? What is the probability that there will be more than one customer waiting in...
