Patients arrive to a small hospital emergency room according to a Poisson process with anaverage rate of 1.5 per hour. Because service times for these patients vary considerably, theservice times are accurately described by an exponential distribution. Suppose that the averageservice time is 26 minutes. If there is only a single doctor working at any point in time, find thefollowing measures of service for this emergency room:The expected total time in the system.b. The expected time each customer has to wait.c. The expected number of patients waiting for service.d. If the emergency room has a triage nurse who gives priority to more serious conditions,explain qualitatively how that would change your results to parts a, b, and c. Whatadditional information would one need to know to analyze a system like this?

As per Bartleby guidelines, we can only solve the first three subparts of one question at a time...Kindly upload the other subparts of the question separately for a quick response.

n a manufacturing process, a molded part spends 7 hours in inventory before being placed in a deburring machine, where the part is processed for 2 minutes. After deburring, the part spends 4 hours in inventory waiting for its turn on the polishing machine. The part then spends 7 minutes in polishing before waiting 6 hours in line to be painted. The part goes through a painting process that takes 7 minutes, then spends 11 hours in inventory before being shipped to the customer. What is the percentage of value-added time for the part?

99) PLEASE HELP ME WITH THIS!! L. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for an injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by up to three nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Let's focus on the simpler case of the two--namely, when there is one nurse. Also, assume that patients arrive in a Poison fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately 4 minutes. It takes the nurse an average of 2.80 minutes to prepare the patients' serum and administer the injection. a. What is the average…
