Question Help ♥ Data collected by a behavioral risk factor surveillance group revealed that in a state, 29.8% of whites and 45.5% of blacks were cigarette smokers. Suppose these proportions were based on samples of 3595 whites and 481 blacks. a) Create a 99% confidence interval for this difference. b) Does this survey indicate a race-based difference in smoking among American adults? Explain, using your confidence interval to test an appropriate hypothesis. c) What alpha level did your test use? a) Let p, be the sample proportion of whites who were cigarette smokers and p, be the sample proportion of blacks who were cigarette smokers. Create a 99% confidence interval for the difference between the two proportions, p,-P2- (Round to three decimal places as needed. Use ascending order.) b) State the hypotheses for the test. Ho H. (Type integers or decimals. Do not round.) State the conclusion. Since the interval the null hypothesis. This study V evidence of a race-based difference in smoking among American adults. c) a= Type an integer or a decimal. Do not round.) does not provide provides
