Question
Problem 1: For the quantitative data (LwT, FTV, BwT) Produce descriptive statistics and one graph for each of these 3 variables, your choice of a boxplot, histogram, or stem and leaf (do one of each). Make some comment/interpretation on the output.

Answer:
There are 189 observations.
The mean value of LWT is 129.81 with standard deviation is 30.58. The median value is 121. The mean is > median and inspection of the graph shows that the distribution of LWT is positively skewed.
The mean value of FTV is 0.7937 with standard deviation is 1.0593. The median value is 0.000. The mean is > median and inspection of the graph shows that the distribution of FTV is positively skewed.
The mean value of BWT is 2944.7 with standard deviation is 729.0. The median value is 2977. The mean is approximately same as median and inspection of the graph shows that the distribution of BWT is approximately bell shaped.
