SIMPLE LOGISTIC REGRESSION

The SIMPLE logistic regression model (M1) for low baby weight (LBW: y = 1 if 10w,y = 0 if not low) on mothers smoking status (:1: = 1 if smoker,a: = 0 if nonsmoker) is estimated as A log( ) = 30 + Blsmoke = 1.087 + 0.704 :1: (M1) 17? Sample Size: Smoker mothers Non-smoker mothers N=115 a) b) C) d) e) f) s) h) Find the estimated odds of LBW for non-smoking mothers. What is the proportion of LBW among non-smoking mothers? Find its 95% Confidence Interval. Find the estimated odds of LBW for smoking mothers? What is the proportion of LBW among smoking mothers? What is the difference of the estimated proportion of LBW between smokers and non- smokers? Find its 95% confidence interval. Plot the estimated regression model. Explain the odds and odd ratio in terms of the graph. What is the estimated odds ratio of LBW for smoking vs non-smoking mothers? Compare the odds ratio with 35101\
