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 d)what is the observed test statistic for this hypthosis test? e) What is the p-value for this hypothesis test f) What is the correct explanation for this hypothesis test? Since the p-value is greater than the level of significance we reject H0 at the 5% level of significance Since the p-value is less than the level of significance we do not reject H0 at the 5% level of significance Since the p-value is greater than the level of significance we do not reject H0 at the 5% level of significance Since the p-value is less than the level of significance we reject H0 at the 5% level of significance

d)what is the observed test statistic for this hypthosis test?
e) What is the p-value for this hypothesis test
f) What is the correct explanation for this hypothesis test?
Since the p-value is greater than the level of significance we reject H0 at the 5% level of significance
Since the p-value is less than the level of significance we do not reject H0 at the 5% level of significance
Since the p-value is greater than the level of significance we do not reject H0 at the 5% level of significance
Since the p-value is less than the level of significance we reject H0 at the 5% level of significance
