Data was collected on life expectancy and six other variables in each of the 50 states and several territories. Unfortunately some states and territories were missing values on some variables. Twelve data points were deleted leading to the remaining data in this file. It is of interest to investigate if it is possible to predict life expectancy from the other variables. Specific questions are listed below. Remember to comment on your work for each problem and sub-problem. Obs state fruitveg obesity tv alcohol cigs poverty lifeexp
