Question: (M/M/∞ model.) Consider a trade fair where visitors arrive according to a Poisson process at a rate of λ = 240 visitors per hour. The time a visitor spends in the trade fair can be modeled as an exponential rv with mean my hours, independent of the number of visitors. Let x(t) be the number of customers in fair at time t.
a) Prove that x(t) is a BDP and determines the birth and death rates.
b) Find the stationary PMD and mean of x(t) and the system stability conditions.
c) Find the probability that the fair is visited by more than M customers in the first 30 minutes after its opening.
d) Find the stationary probability of having more than M customers in the fair at any given time.
Construct a stem-and-leaf display for these data.- Construct a frequency distribution for these data.- Determine the interval width and the class mark for each of the classes in your frequency distribution.
Compare the mean absolute error, root mean square error, and the mean absolute percent of error for all four of these forecasting techniques - what do these statistics tell you about the forecasts? Which one is the best forecast and why?
The data set labcomp .txt is the result of an "inter-lab" study where multiple labs, in this case each located at a different plant, participate in a study to compare measurements within and between the labs.
At a casino, people play the slot machines in hopes of hitting the jackpot, but most of the time, they lose their money. A certain machine pays out an average of $0.92 (for every dollar played), with a standard deviation of $120.
Use the Wilcoxon rank-sum test with a = 0.05 to determine whether there is any evidence to suggest that the population median visit times are different.

BLACKJACK In the game of blackjack, a 2-card hand consisting of an ace and a face card or a 10 is called a blackjack.
Clinic evaluates that true population standard deviation is around $1,300. If confidence level is 95%, determine the required sample size in order to meet desired accuracy.
In a compressed data file of 10,000 bytes, each byte is equally likely to be any one of 256 possible characters b0,..., b255 independent of any other byte. If Ni is the number of times bi appears in the file, find the joint PMF of N0,..., N255. Also,..
