Problem 7 You're a healthcare engineering consultant and you're analyzing the emergency room design at Pawhuska Hospital, Inc. To understand the service rate of the ER, you must first analyze the arrival of patients, and you begin by studying the overnight arrivals. The probability distribution is shown in the table. Plot the cumulative distribution function of hourly patients arriving to the ER. Calculate the mean and standard deviation of the probability distribution of hourly ER arrivals. What is the probability...
Problem 5 You're a healthcare engineering consultant and you're analyzing the emergency room design at Pawhuska Hospital, Inc. In homework 8.xlsx you'll find sample data for the waiting time of non- critical patients entering the emergency room. You realize that there's going to be some variability in the waiting time of patients given how different their circumstances are (even if all are non-critical), but you'd like for the standard deviation of waiting times to be less than 35 minutes, what...
Patients arriving at the emergency room of a local hospital follow a Poisson distribution with an average arrival rate of 26 per half hour. Find the probability that between 32 and 35 patients (inclusive) will arrive at the emergency room within a half hour. Round your answer to four decimal places, if necessary.
PROBLEM 18.1 (pg 132, #86) People randomly arrive for treatment at an emergency room at a rate of 3.8 per hour. Let Y be the amount of time (in hours) until the next patient arrives in the emergency room. a. The random variable Y has an exponential distribution with parameter λ b. Find the probability no patients arrive over the next 2 hours or P(Y> 2). c. Find the median of Y d. What is the expected elapsed time until...
