A state-by-state survey found that the proportions of adults who are smokers in state A and state B were 18.1% and 22.6%, respectively. (Suppose the number of respondents from each state was 3000.) At a = 0.01, can you support the claim that the proportion of adults who are smokers is greater in state A than in state B? Assume the random samples are independent. Complete parts (a) through (e). (a) Identify the claim and state H, and Ha. The claim is "the proportion of adults who are smokers in state A is the proportion of adults who are smokers in state B." Let p, and p2 be the two population proportions. State H, and H, Choose the correct answer below. O A. Ho P12 P2 Ha P1
