The number of persons coming through a blood bank until the first person with type A blood is found is a random variable with a geometric distribution. If denotes the probability that any one randomly selected person will possess type A blood, then E(= 1/and V((1 - p)/p2.

a. Find a function of that is an unbiased estimator of V().

b. Suggest how to form a 2-standard-error bound on the error of estimation when is used to estimate 1/p.
