For this problem we will use the birthwt dataset that is available in the MASS package (recall how to access it by looking at past homeworks). We are interested in the relationship between the smoke column of the datset and the low column of the dataset.
1. Make a frequency table for low versus smoke.
2. Make a relative frequency bar graph for low versus smoke. Give the different variables different colors when making the plot.
3. Make a boxplot for bwt versus smoke. Label the plot appropriately.
4. Make a scatterplot of bwt versus age. Based on the graph, does there appear to be any association between age and bwt? Describe briefly. Keep in mind that age denotes the mothers age, and bwt denotes the baby's weight in grams.
