Let 3, 1,3,0, 3, 2, 2, 0, 1, 2 be ten independent observations from a binomial experiment four
independent trials each with probability of a success B and PMF f(x,B).
i) If = 0.35, derive an approximate standard error of .
ii) Compute a 95% confidence interval for B.
b) Suppose that a random variable X has a probability density function given as
(2(B-x)
f(x; B)= B² 0<x<B
elsewhere
i) Use an appropriate method to show that W = is a pivotal quantity.
ii) Construct a 90% upper confidence limit for B, using part i) of Question 4 b).
