"Mega Grocery (MG)" at Atwater operates six checkout counters, each serving its own waiting line. On average, 90 customers per hour are arriving to MG following Poisson distribution. The service time is 3 minutes per customer following exponential distribution. The waiting cost of a customer in the system is $40 per hour. MG is employing one worker at each checkout counter at an hourly wage of $30. Suppose all customers are pooled into a single queue, how many checkout counters would be optimum?

Suppose an oceanographer monitors the daily salinity of a particular ocean in relation to the temperature of the water. The oceanographer plots the data with temperature, in degrees Celsius (°C), along the horizontal axis and salinity, in parts per thousand (ppt), along the vertical axis. Select the true statement about the data point identified by the arrow. An ocean temperature of 21 °C causes the salinity to be 29 ppt. The predicted salinity is 29 ppt when the ocean temperature for the day is 21 °C. An ocean temperature of 29 °C corresponds to a salinity level of 21 ppt. The observed salinity is 29 ppt when the ocean temperature for the day is 21 °C. There is no relationship between the temperature of the ocean on a given day and salinity.

In 2015, over 30,000 Americans died from opioid overdoses, and the number of inpatient stays and emergency visits to hospitals related to opiods increased dramatically compared to previous years. The National Institutes of Health (NIH) have partnered with the Healthcare Cost and Utilization Project (HCUP) to gather data on opioid-related deaths and hospitalizations. These data include information about inpatient stays, emergency department visits, age, sex, income, and opiod-related use. For a given patient admitted to a hopsital for an opioid-related event, identify which of these events are disjoint. The patient stayed at the hospital for over a week. The patient was 62 years old. The patient was male. The patient's duration of stay was one day. The patient was admitted to a large metropolitan hospital.
A hospital has two operation rooms. The service times for each of them is exponentially distributed with mean 17 minutes and are supposed to be independent. When both operation rooms are not busy then Akbar arrives. Whereas Bilal arrives 12 minutes later while Akbar is still under medication.After another 20 minutes later, Sameer arrives and both Akbar and Bilal are still under the medical treatment. There is no other arrival of any patient during this 40-minute time period.(a). Find the probability that Akbar will be ready before the Bilal’s arrival?(b). Find the probability that Sameer will be ready before Bilal’s arrival?(c). Find the probability that Sameer will be ready before Bilal’s arrival?(d). Calculate the waiting time for Sameer in the system?
A study-aid desk staffed by a graduate student has been established to answer students' questions and help in working problems in your OSCM course. The desk is staffed eight hours per day. The dean wants to know how the facility is working. Statistics show that students arrive at a rate of six per hour and the distribution is approximately Poisson. Assistance time averages 6 minutes, distributed exponentially. Assume population and line length can be infinite and queue discipline is FCFS. a. Calculate the percentage utilization of the graduate student. (Round your answer to 1 decimal place.) b. Calculate the average number of students in the system, including the graduate student service desk. (Round your answer to 1 decimal place.) c. Calculate the average time in the system. (Round your answer to 1 decimal place.) d. Calculate the probability of four or more students being in line or being served. (Round your intermediate calculations to 3 decimal places and final answer to 1 decimal…
23. A population of 30 chemical processing units is to be sampled by a two-person crew. The mean time between calls for this operation is 68 minutes. If the mean service rate is one unit per minute, the cost of the crew and instruments will be $16 per minute. This cost will decrease to $12, $9, and $7 for service intervals of 2,3, and 4 minutes, respectively. The time between calls for service and the service duration are distributed exponentially. If lost profit is $28 per hour for each unit that is idle, find the minimum cost service interval.

Customers arrive at a check-out counter in a supermarket in a Poisson fashion at a rate of 8 customers per hour. The supermarket has one cashier only. The check-out time is exponentially distributed with a mean of 3.204 minutes. Assume the queue discipline is first in first out (FIFO). Use Arena to simulate the system, run one replication for 10,000,000 minutes (10 million minutes), use minutes as the base time unit. Choose the nearest answer for the following. Note: No need to upload your Arena Model The server utilization Choose. + The average time in the queue; Choose. The probability that the server is idle Choose.

A researcher thinks some social media sites are more prone to narcissistic behavior (excessive posting) than others. To examine the relationship between narcissism and social media, she recruits users of three different social media sites (Facebook, Twitter and Instagram), follows them for 24 hours and records the number of posts made by each user. The number of posts is given in the table below. Twitter Facebook Instagram 10 7 14 10 8. 10 10 10 11 9. www. 12 wwww. 11 13 12 8. 7 8. 11 8 10 12 11 11 a.

Is there a link between dark chocolate and weight loss when compared to milk chocolate? A nutritionist gathers 60 people, selected at random, then randomly assigns half of the group to eat a single dark chocolate bar after dinner each night and the other half to eat a single milk chocolate bar after dinner each night for 6 months. Everyone is to keep track of the other food they eat in an app provided. The nutritionist then compares each person’s weight after the 6 months to their weight before eating the different chocolates accounting for the other calories consumed. 12) What type of study does this describe? a) Survey b) Observational study c) Experimental study
You set up a series of cameras along the Mexican border. The rate of appearances of Jaguars is 4/18 years. Your cameras also produce pictures of wolf-sized canids, either wolves or coy-wolves in the same region. Each year your cameras catch about 400 of these animals, about 60 cougars and about 700 bears and 1200 feral hogs. Assume that these numbers are all population rates for Poisson. Given your cameras catch a non human large animal (and the above list is all of them): i. What is the probability it is a jaguar? (Hint: Animals are independent. This is asking the conditional probability of a jaguar, given you see an animal) ii. What is the probability it is a feral hog? iii. Out of 25 large nonhuman animals, what is the probability that 15 or more are feral hogs? (Hint N=25, P is fixed, independent trials) iv. Out of 180 large non human animals what is the probability that between 100 and 170 are feral hogs?
Urgent Care is organized in to 4 department: Registration (Reg), Waiting (Wait), Treatment (Treat), and Payment & Check Out (PCO). For all patients who receive treatment at the Urgent Care, the expected time (in minutes) per patient needed in each of the departments: Reg. Wait. Treatment PCO 10 15 30 3 or 2 All patients enter and register at the registration cubicle. After registering, 10% of the patients walk out without waiting and seeing the physician for treatment. However, still they have to walk through the PCO & return the admissions slip. These patients need only 2 min at PCO (instead of 3 min). No waiting and treatment time for patients who walk out. Simulate the total time spent in the Urgent care for the first patient. Total time spent by Patient 1 at the Urgent Care is .
