For the following information, determine whether a normal sampling distribution can be used, where p is the population proportion, a is the level of significance, p is the sample proportion, and n is the sample size. If it can be used, test the claim. Claim: p20.47; a = 0.06. Sample statistics : P = 0.40, n = 150 Let q=1-p and let = 1-P. A normal sampling distribution be used here, since v and If a normal sampling distribution can...
