With reference to Exercise 4.71, what can we assert about the amount of time it takes a person to be served at the given restaurant if we use Chebyshev’s theorem with k = 1.5? What is the corresponding probability rounded to four decimals?
Answer to relevant QuestionsA quarter is bent so that the probabilities of heads and tails are 0.40 and 0.60. If it is tossed twice, what is the covariance of Z, the number of heads obtained on the first toss, and W, the total number of heads obtained ...If we alternately flip a balanced coin and a coin that is loaded so that the probability of getting heads is 0.45, what are the mean and the standard deviation of the number of heads that we obtain in 10 flips of these ...With reference to Exercise 5.12, find the factorial moment–generating function of (a) The Bernoulli distribution and show that µ'(1) = . and µ'(r) = 0 for r > 1; (b) The binomial distribution and use it to find µ and ...Use the moment–generating function derived in Exercise 5.20 to show that for the geometric distribution, µ = 1/θ and σ2 = 1 – θ / θ2. We did not study the Bernoulli distribution in any detail in Section 5.3, because it can be looked upon as a binomial distribution with n = 1. Show that for the Bernoulli distribution, µ'r = θ for r = 1, 2, 3, . . ., ...
