When dealing with a waiting line problem in which the arrivals follow a poisson distribution, and the service times are either exponential or follow an arbitrary distribution with a known mean and standard deviation, list three ways in which the performance of a system can be improved. Discuss the advantage and disadvantage of each one.

Assume that the number of defects in a car has a Poisson distribution with parameter 𝜆.

Assume that the number of defects in a car has a Poisson distribution with parameter 𝜆. To estimate 𝜆 we obtain the random sample 𝑋1,𝑋2, … , 𝑋n.a. Find the Fisher information is a single observation using two methods.b. Find the Cramer-Rao lower bound for the variance of an unbiased estimator of 𝜆.c. Find the MLE of 𝜆 and show that the MLE is an efficient estimator.

For the Poisson Distribution a. Is λ×T a parameter of position, scale, shape or a combination?...

For the Poisson Distribution a. Is λ×T a parameter of position, scale, shape or a combination? Explain. b. We can treat “λ×T” as a single parameter, but they actually represent two parameters: λ and T. Say you stand by the side of the road and count the number of cars that pass by you in one minute. After repeating this process 10 times you find the average number of cars that pass in 10 minutes. In this case, what is...

Let XiXi for i=1,2,3,…i=1,2,3,… be a random variable whose probability distribution is Poisson with parameter λ=9λ=9. Assume the Xi are independent. Note that Poisson distributions are discrete. Let Sn=X1+⋯+Xn. To use a Normal distribution to approximate P(550≤S64≤600), we use the area from a lower bound of __ to an upper bound of __ under a Normal curve with center (average) at __ and spread (standard deviation) of __ . The estimated probability is __

This question is based on a Poisson discrete probability distribution. The distribution is important in biology and medicine, and can be dealt with in the same way as any other discrete distribution. Red blood cell deficiency may be determined by examining a specimen of blood under the microscope. The data in Table B gives a hypothetical distribution of numbers of red blood cells in a certain small fixed volume of blood from normal patients. Theoretically, there is no upper limit...

Suppose passengers arrive at the MTA train station following a Poisson distribution with parameter 9 and the unit of time 1 hour. Next train will arrive either 1 hour from now or 2 hours from now, with a 50/50 probability. i. E(train arrival time) ii. E(number of people who will board the train) iii. var(number of people who will board the train)

The demand for a replacement part is a random variable having a Poisson probability distribution with a mean of 4.7. If there are 6 replacement parts in stock, what is the probability of a stock-out (i.e., demand exceeding quantity on hand)?
