Patient arrivals at a hospital emergency department follows a Poisson distribution and the waiting time for service follows an exponential distribution with a mean of 2.75 hours. Determine the following: (a) Probability that the waiting time exceeds four hours (b) Value for waiting time (in hours) exceeded with probability 0.35.
A juicer works for T amount of time before it breaks, where T follows the exponential distribution with rate = 3. After sales service examines the juicer at times distributed according to a Poisson process with rate = 2; if the juicer is found to be not working then it is immediately substituted. 1) Find the probability that a juicer is examined at least 2 times before it stops working. 2) Find the expected time between replacements of juicers. We...
1. After having estimated a regression model , we wish to forecast the value of given a new observation . We can consider two types of predictions: forecasting the conditional mean of , or forecasting the actual value of . What is true about the variances of these predictions? Var[conditional mean] > Var[actual value]. Var[conditional mean] = Var[actual value]. Var[conditional mean] < Var[actual value]. Var[conditional mean] may be larger than Var[actual value] in some data sets and smaller in others....
A Pareto distribution is often used in economics to explain a distribution of wealth. Let a random variable X have a Pareto distribution with parameter θ so that its probability distribution function is for and 0 otherwise. The parameters and are known and fixed; is a constant to be determined. a) Assuming that find the expected value and variance of ? b) Show that for 3 ≥ θ > 2 the Pareto distribution has a finite mean but infinite variance,...
