Data table D-E15

Could it be that smoking actually increases survival rates among women? The accompanying data represent the 20-year survival status and smoking status of women who participated in a 20-year cohort study. Complete parts (a) through (e). Click the icon to view the data table. (b) The data in the first table do not take into account a variable that is strongly related to survival status, age. The data shown in the second accompanying tabl give the survival status of women and their age at the beginning of the study. For example, 14 women who were 35 to 44 at the beginning of the study were smokers and dead after 20 years Determine the proportion of 18-to 24-year-old smokers who were dead after 20 years. The proportion of 18- to 24-year-old smokers who were dead after 20 years is (Round to three decimal places as needed.) Determine the proportion of 18-to 24-year-old nonsmokers who were dead after 20 years The proportion of 18- to 24-year-old nonsmokers who were dead after 20 years is (Round to three decimal places as needed.) (c) Repeat part (b) for the remaining age groups to create a conditional distribution of survival status by smoking status for each age group Age Group Click to select your answer(s)
