Please answer as neatly as possible. Much thanks in advance! Question 1: 6. In Problem 1, show that θ2 is a consistent estimator for θ. Deduce that Y(n) is a consistent estimator for θ and also asyınpt○tically unbiased estimator for θ. 1. Let Yi, ½, . . . ,y, denote a random sample from an uniform distribution on the interval (0,0). We have seen that (1) and 62 Ym are unbiased estimators for 0. Find the efficiency of 6 relative...
Consider the binomial distribution with parameters n 10 and p (unknown) a) Is this binomial distribution an exponential family distribution? b) Find a sufficient statistic for p.
Exercise 1: Let Y be a binomial distribution of parameters n = 10 and p = 0.4. Determine the normal approximation for: a) P (Y ≥ 7) Exercise 2: The quality control of an automobile manufacturer accuses 1% of failures in the process of antioxidant protection of bodywork of the vehicles it produces. Calculate the probability that: a) none of the 100 vehicles ordered by a dealership has the aforementioned failure; b) only one vehicle has the fault mentioned in...
Use simulations to prove that the binomial distribution is correct. The binomial distribution has two parameters n and p. There are n trials and each has two possible outcomes, with probability p for “success” and 1-p for “failure”. The binomial gives the probability distribution for the number of successes in n trials. You will conduct simulations with r replicates, where each simulation replicates does n simulated “coin flips”. You will add up the number of successes in each coin flip,...
Let M have a binomial distribution with parameters N and p. Conditioned on M, the random variable X has a binomial distribution with parameters M and (a) Determine the marginal distribution for X (b) Determine the covariance between X and Y M- X
Exercise 2.37 If X has the binomial distribution with parameters n and p- 1-q, show that E(X) = np, E(X2) = npq + n2 p2. and deduce the variance of X
Identify the parameters p and n in the following binomial distribution scenario. The probability of winning an arcade game is 0.718 and the probability of losing is 0.282. If you play the arcade game 20 times, we want to know the probability of winning more than 15 times. (Consider winning as a success in the binomial distribution.) p= n=
