Messages arrive at an electronic mail server at the average rate of 4 messages every 5 minutes. Their number is modeled by a Binomial counting process.
(a) What frame length makes the probability of a new message arrival during a given frame equal 0.05?
(b) Suppose that 50 messages arrived during some 1-hour period. Does this indicate that the arrival rate is on the increase? Use frames computed in (a).

Question 4 (1 point) ✓ Saved Jobs are sent to a printer at the average rate of 2 jobs per minute. Binomial counting process is used to model these jobs. What frame length in seconds gives the probability 0.08 of an arrival during any given frame? 9.6 25 2.4 4.8 5.2
At an urgent care facility, patients arrive at an average rate of one patient every 6 minutes (that is λ-6). Assume that the duration between arrivals is exponentially distributed 1) (a) Find the probability that the time between two successive visits to the urgent care fa- cility is less than 4 minutes. (b) Find the 75th percentile. That is, determine To.75 (c) Find the probability that more than 6 patients arrive during a half-hour period.
4 (5 points) The average number of text messages is arrived at a rate of 2 messages per mmute. The probability that, in a 5-minute period, at most one message arrives can be compuled as e 10100 e 10101 e-22 2 C. -200 e 221 a. b. 0! 1!
Autos arrive at a toll plaza located at the entrance to a bridge at a rate of 10 per minute during the 5:00-to-6:00 P.M. hour. Determine the following probabiiies assuming that an auto has just arrived. a. What is the probability that the next auto will arrive within 6 seconds (0.1 minute)? b. What is the probability that the next auto will arrive within 3 seconds (0.05 minute)? c. What are the answers to (a) and (b) if the rate...
Please answer using stochastic operations principles Cars arrive at a rate of 10 per hour in a single-server drive-in restaurant. Assume that the teller serves vehicles with a rate exponentially distributed with a mean of 4 minutes per car (ie, a rate of 1 car every 4 minutes). Answer the following questions: (a) What is the probability that the teller is idle? (b) What is the average number of cars waiting in line for the teller? (A car that is...

Find (a) the probabilities that (G) during 6 hours no customers will arrive, (i) at most twenty five customers will arrive; (b) the probabilities that the waiting time between the third and the fourth customers will be (i) greater than 30 min.,(ii) equal to 30 min., (ii)i greater than or equal to 30 min. (c) the probability that after the first customer has...
During lunchtime at a certain fast food restaurant, customers arrive at an average rate of 7 customers every 5 minutes. assume a poisson distribution to find the probability that: A) exactly 12 customers arrive in a given 10 minute interval (perform this calculation using an appropriate formula, showing the setup.) b) between 5 and 10 customers (inclusive) arrive in a given 5 minute interval (show how you can answer this from the table) c) after a customer arrives, find the...
