Question 5 The waiting time in the emergency department in a large hospital is a concern for the outdoor patients. Based on the historical records of the hospital, it is found that the mean and standard deviation of waiting time of patients in the emergency department are 40 minutes and 6 minutes respectively. Assume that the distribution of waiting time follows a normal model. For the waiting time of a random sample of 25 patients from the population of patients...

(b) What is the probability that the arrival time between vehicles is 11 seconds or less? (c) What is the probability that the arrival time between vehicles is 7 seconds or less? (d) What is the probability of 33 or more seconds between vehicle arrivals?
During the COVID-19 pandemic, the hospital emergency department at a very busy hospital receives, on average, 23.6 patient per day. The standard deviation of inter-arrival time between two consecutive patients arriving is 6.9 minutes. What is the coefficient of variation for the inter-arrival times (times between two consecutive arrivals) for patients arriving (received at) at the hospital’s emergency department? Note that, the emergency service of this hospital is open 24/7, and one day is equivalent to 24 hours.

Please show steps on excel. Thank you. In a waiting line situation, arrivals occur around the clock at a rate of six per day, and the service occurs at one every three hours. Assume the Poisson and exponential distributions. What are μ and λ ? Find probability of no units in the system. Find average number of units in the system. Find average time in the waiting line. Find probability that there is one person waiting.
