A state-by-state survey found that the proportions of adults who are smokers in state A and state B were 24.6% and 19.3%, respectively. (Suppose the number of respondents from each state was 2000.) 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 Ho and Ha The claim is "the proportion of adults who are smokers in state A is smokers in state B." Let p and p2 be the two population proportions. State Ho and Ha. the proportion of adults who are the same as Choose the correct answer below. A. Ho: P1 P2 Ha: P1 P2 B. Ho: P1 P2 Ha: P1 P2 lower than 1 P2 P = P2 different than D.
