A new campaign is under construction to increase the awareness of the risks a newborn might be facing because of smoking. A) To make sure this campaign's message reaches at least 54% of women who smokes(during pregnancy only) and are pregnant, find a 95% confidence interval for the age of women that this campaign should target. (hint: check Gestation help help ("Gestation") document to select women who smoke during current pregnancy) B) Does smoking affects baby's weight? i) From the Gestation data, pick the sample of baby's weight for women who never smoked, then resample from that sample (1000 times, i.e. use sample Dist function) to find an estimate for the average weight of newborn for women who never smoked. ii) Next, test the hypothesis that the average weight of babies (of women who smokes, this includes: still smoke or during current pregnancy) is less than that of non-smoking mothers (i.e less than value obtained in part i). Use 5% level of significance.
