Suppose you took 1000 random samples of size 200 from the Poisson distribution

with u = 5 and computed a 90% confidence interval for each sample. Approximate the probability that at

least 920 of these intervals would contain the mean value u = 5. Be sure to define any random variable you

use, as well as its distribution, and justify any procedure that you use.

the u represent mu sign
