1. The unit of observation is births. There are 14 different variables. Female age – numerical Male age – numerical Mature – categorical Weeks – numerical Premie – categorical Visits – numerical Martial – categorical Racemom – numerical Hispmom – categorical Gained – numerical Weight – numerical Lowbirthweight – categorical Sexbaby – categorical Habit - categorical 2. There are 126 smokers. 12.6% of the mothers are smokers 3. I believe that low birth weight will be affected by whether or not the mother is a smoke or not. Of the low birthweights, 16% were smokers, while 83% of the lowbirth weights were non smokers. Similarly 12% of the not low birth weights were smokers. Thus this shows that there is no clear association with low or not low birth weights and smoking, and my hypothesis was wrong.
