Question 2 [25 Points! The data on low birth weight was derived from a case-control study of 189 live births. Babies with birth weight below 2.5 kilograms were considered cases and the rest were treated as controls. Maternal characteristics such as age, race (1=white, 2=black, 3=other), smoking status (1=yes, 0=no), and history of U1 were among the many exposures considered. For this exercise, we are interested in whelther history of hypertension is a risk factor for low birth weight. To investigate this, you will need perform the following: 1) Analyze the crude association between hypertension (HT) and low birth weight; 2) Identify potential confounders or effect modifiers among the variables listed above. To do this, you will first need to complete the Table 1 attached, conduct stratified analysis, and assess stratum specific OR's to identify effect modifiers or report adjusted rates. 3) Perform logistic regression to determine the adjusted and possibly stratum specific association between low birth weight and HT. 4) Summarize your results and state your conclusions.th
