Explore HDL and BMI results
In this exercise, you'll explore simulation results for two variables: bmi and hdl. The simulated results for differences in predicted y values for people in the fourth quantile compared to the first quantile for each predictor (one at a time) have been generated and loaded as df_diffs for you. 
The following libraries have been imported: pandas as pd, numpy as np, scipy.stats as st, matplotlib.pyplot as plt, and seaborn as sns. The diabetes dataset, dia, is also loaded.
