Question
A state by state survey found that proportion of adults who are smokers in state A and B were 25.4 % and 22.5%, respectively. (Suppose the numbers of respondents from each state was at 3000.) at a= 0.05, 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.

At a =0.05, can you support the claim that the proportion of adults whe are smokers is greater in state A than in state B? Assume the random samples are independent. Complete parts (a) through (e). Identify the rejection region(s). Choose the correct answer below. O A. z> 1.64 O B. z>1.96 O C. z< -1.64, z>1.64 O D. zs1.64 O E. z<1.96 OF. z<-1.96, z>1.96 (c) Find the standardized test statistic. =(Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. Reject Ho Fail to reject H- (e) Interpret the decision in the context of the original claim.
