- Table 3 shows the number of lung cancer deaths per daily number of cigarettes smoked at the time of completing the 1951 questionnaire (only for male physicians who were nonsmokers and current smokers). The number of cigarettes smoked was available for 136 of the people who died of lung cancer. Number of cigarettes Deaths 3 Person-years 42800 0. 1-14 22 38600 15-24 54 38900 +24 57 25100 a) Estimate the appropriate measure of association and 95% confidence interval for each category of number of cigarettes smoked daily, using the group of non-smokers as the reference category. b) What can be inferred about the estimated measure of association in the different categories of number of cigarettes smoked daily? c) What is the proportion of lung cancer deaths among all smokers that can be attributed smoking? What is the proportion of lung cancer deaths in the total population that can be attributed to smoking? consider thatFind the z score for test scores of 70 _____ and 90 ______.If the coefficient of determination between two independent variables is 0.14, what is the VIF?

The aphids were collected in 6 galls on the cottonwood, Populus deltoides. Four alate (winged) aphids were randomly selected from each gall and measured. The alate aphids of each gall are mostly isogenic (identical twins), being decended parthenogenetically from one stem mother. Thus, any variance within galls should be due to environment only. Variance among different galls may be due to differences in genotype and also to environmental differences among galls. Do a one-way ANOVA to test whether there significant intergall variance.
