Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the giver using the given sample statistics. Claim: p#0.24; a = 0.01; Sample statistics: p = 0.22, n = 200 Can the normal sampling distribution be used? Yes, because both np and nq are greater than or equal to 5. O B.
