# Question: The number of complaints that a dry cleaning establishment receives per

The number of complaints that a dry-cleaning establishment receives per day is a random variable having a Poisson distribution with θ = 3.3. Use the formula for the Poisson distribution to find the probability that it will receive only two complaints on any given day.

The number of monthly breakdowns of a super computer is a random variable having a Poisson distribution with θ = 1.8. Use the formula for the Poisson distribution to find the probabilities that this computer will function ...The probabilities are 0.40, 0.50, and 0.10 that, in city driving, a certain kind of compact car will average less than 28 miles per gallon, from 28 to 32 miles per gallon, or more than 32 miles per gallon. Find the ...Use the recursion formula of Exercise 5.8 to show that for θ = 12 the binomial distribution has (a) A maximum at x = n/2 when n is even; (b) Maxima at x = n – 1 / 2 and x = n + 1 / 2 when n is odd. In exercise (a) In Exercise 5.92 change the acceptance number from 1 to 0 and sketch the OC curve. (b) How do the producer’s and consumer’s risks change if the AQL is 0.05 and the LTPD is 0.3 in both sampling plans?
