5. a. By how much must the sample size n be increased if the width of the Cl is to be halved? If the sample size is increased by a factor of 25, what effect will this have on the width of the interval? Justify your assertions. b. Let (11,1512 > 0 with (:1 + a2 = 0:. Then P(zc1 Sa/JHSZ'\"): la. Use this equation to derive a more general expression for :1 100(1 00% CI for ,u. a 3\"! Let a: = 0.05 and a1 = 2 (:2 = T" Does the general expression result in a narrower or wider interval than the standard interval with a
