Question
Please answer the Question (a) for me Thank you Business Stats ASPIRIN fo 2.141 More smokers live at least 20 more years! You can see the headlines "More smokers than non- smokers live at least 20 more years after being con- tacted for study!" A medical study contacted randomly chosen people in a district in England. Here are data on the 1314 women contacted who were either current smokers or who had never smoked. The tables classify these women by their smoking status and age at the 20 years later.29 SM Age 18 to 44 Age 45 to 64 Smoker Not Smoker Not Smoker Not Age 65+ Dead 19 3 78 52 42 165 Alive 269 327167 147 28 (a) From these data. make a two way table of smoking (yes or no) by dead or alive. What percent of the smokers stayed alive for 20 years? What percent of the nonsmokers survived? It seems surprising that a higher percent of smokers stayed alive. (b) The age of the women at the time of the study is a lurking variable. Show that within each of the three age groups in the data, a higher percent of nonsmokers remained alive 20 years later. This is another example of Simpson's paradox.Explanation / Answer
for adding all smokers and not smokers category wise below is 2 way table:
therefore % of smokers alive for 20 years =(443/582)*100 =76.12%
% of non smokers alive for 20 years =(502/732)*100 =68.58%
