i. Identify the null and alternative hypothesis. i. State the decision rule. i. Compute for the test statistic. iv. Do we reject the null hypothesis at the specified level of significance? v. Interpret the results. In a study to estimate the proportion of smokers among the residents in a certain city and its suburbs, it is found that 24 of 104 urban residents are smokers, while 34 of 108 suburban residents are smokers. a. Is there a significant difference between the proportions of smokers among urban and suburban residents? Test the hypothesis using a 0.01 level of significance. b. Create a 99% confidence interval estimate of the difference of proportion of residents who smokes between urban and suburban residence. Interpret the computed confidence interval.
