14. Apply the weak law of large numbers to determine the necessary sample size in the following cases to have 95% confidence:

(a) For the geometric distribution, estimate the unbiased variance to one decimal place, where it is know that p > 0:25 (Hint: For the geometric, m4 ¼ q p2 1 þ 9q p2



.)

(b) For the Poisson distribution, estimate l to two decimal places where it is known that l > 2.
