The manager of a grocery store in the retirement community of Sunnyville is interested in providing good service to the senior citizens who shop in her store. Currently, the store has a separate checkout counter for senior citizens. On average, 30 senior citizens per hour arrive at the counter, according to a Poisson distribution, and are served at an average rate of 35 customers per hour, with exponential service times. Find the following operatingcharacteristics:a. Probability of zero customers in the systemb. Average utilization of the checkout clerkc. Average number of customers in the systemd. Average number of customers in linee. Average time spent in the systemf. Average waiting time in line
he management of a supermarket wants to adopt a new promotional policyof giving free gift to every customer who spends more than a certain amountper visit at this supermarket. The expectation of the management is that afterthis promotional policy is advertised, the expenditure for all customers at thissupermarket will be normally distributed with mean 400 L.E and a variance of900 L.E23) What is a probability of selecting a customer whose expenditure is differthan the population mean expenditure by at most 50 L.E?4) What is the percentage of customers whose expenditure is at least 450L.E.?
A new automated production process averages 3.5 breakdowns per day. Because of the cost associated with a breakdown, management is concerned about the possibility of having three or more breakdowns during a day. Assume that breakdowns occur randomly, that the probability of a breakdown is the same for any two time intervals of equal length, and that breakdowns in one period are independent of breakdowns in other periods. What is the probability of having three or more breakdowns during a day?.
The management of a supermarket wants to adopt a new promotional policy of giving free gift to every customer who spends more than a certain amount per visit at this supermarket. The expectation of the management is that after this promotional policy is advertised, the expenditure for all customers at this supermarket will be normally distributed with mean 400 £ and a variance of 900 £2. 4) In a sample of 49 customers, what are the number of customers whose mean expenditure is at least 410 £?5) What is the probability that the expenditure of the first customer exceeds the expenditure of the second customer by at least 20 £?
One of the earliest applications of the Poisson distribution was in analyzing incoming calls to a telephone switchboard. Analysts generally believe that random phone calls are Poisson distributed. Suppose phone calls to a switchboard arrive at an average rate of 2.4 calls per minute.a. If an operator wants to take a one-minute break, what is the probability that there will be no calls during a one-minute interval?b. If an operator can handle at most five calls per minute, what is the probability that the operator will be unable to handle the calls in any one-minute period?c. What is the probability that exactly three calls will arrive in a two-minute interval?d. What is the probability that one or fewer calls will arrive in a 15-second interval? a. P(x = 0 | λ = 2.4) = b. P(x > 5 | λ = 2.4) = c. P(x = 3 | λ = 4.8) = d. P(x ≤ 1 | λ = 0.6) =
The arrival rate of patients at a hospital counter follows Poisson distribution with a mean of 25 per hour. The service rate of the treatment to patients also follows Poisson distribution with a mean of 45 per hour.What is the probability of having 10 patients in the system (P 5 )?
The arrival of patients in a hospital follows the Poisson process at a rate of 8 people/hour.a. Find the probability that 5 patients present in the first hourb. What is the probability that the time between arrivals of the 4th and 5th patients is more than 1/2 hour?c. What is the probability that the arrival time of the second patient is more than 1 hour?What is the mean and variance of time until the arrival of the 8th patient?
A project manager is attempting to estimate the time that will be required to complete an initial assessment of the capital project of constructing a new corporate headquarters. There is considerable uncertainty regarding the duration of these tasks, and generally little or no historical data are available to help estimate the probability distribution for the time required for this assessment process. Suppose that we are able to discuss this project with several subject-matter experts who have worked on similar projects. From these expert opinions and our own experience, we estimate that the minimum required time for the initial assessment phase is six months and that the worst- case estimate is that this phase could require 24 months. The experts stated that the most likely amount of time required for the initial assessment phase of the project is 12 months. a. Calculate the probability that the time required is less than 12 months b. Calculate the probability that the project…
A pharmaceutical company receives large shipments of ibuprofen tablets and uses sampling plan to accept the shipmemts. They randomly select and test 27 tablets, and accept the entire batch if there is at most one tablet that does not meet the required specifications.Suppose a particular shipment of ibuprofen tablets has a 4% rate of defects. What is the probability that this whole shipment will be accepted?
