Let p1 denote the proportion of ault males in Australia that smoke and let p2 denote the proportion adult females in Australia that smoke. A simple random sample of 1535 individuals were randomly selected from adult male population in Australia and it was found that 352 of them smoked. A simple random sample of 1521 individuals were randomly selected from adult female population in Australia and it was found that 301 of them smoked. Researchers want to test, at the 5% level of significance, the null hypothesis H0: p1-p2=0.03 vs the alternative hypothesis Ha:p1-p2<0.03. Suppose the assumptions to this hypothesis are satisifed a) What is the deciison rule for this hypothesis test? b)What is the proportion of males in the sample that smoke? c)What is the proportion of females in the sample that smoke
