Part1

For each of the four datasets...

• Compute the mean and variance of both x and y

• Compute the correlation coefficient between x and y

• Compute the linear regression line: y=β0+β1x+ϵy=β0+β1x+ϵ (hint: use statsmodels and look at the Statsmodels notebook)

Part 2

Using Seaborn, visualize all four datasets.

hint: use sns.FacetGrid combined with plt.scatter
