The assignment should be done using R statistical software. No manual calculations are allowed Please turn in all codes and corresponding outputs The assignment should be typed in. Consider the dataset in "Birth.txt", which represents the data on 189 women who gave birth to either a low weight baby (weighing less than 2500 grams) or a normal weight baby. The objective of the study was to identify the risk factors associated with giving birth to a low birth weight baby. The researchers identified three variables that might influence the birth weight of babies: age of the subject in years, weight of the subject in pounds, and smoking status during pregnancy (1 = Yes, 0 = No). The actual birth weights (in grams) of babies are presented in the column BW (Hosmer, D.W., Lemeshow, S. and Sturdivant, R.X., 2013)
