Samples from multivariate normal distributions

The multivariate normal is the most important distribution in multivariate statistics. Here, you will learn to simulate data that follow a specified multivariate normal distribution by generating samples from a bivariate normal distribution, with a mean and variance-covariance matrix specified as:

$${\boldsymbol \mu }={\begin{pmatrix} 2 \\ -2 \end{pmatrix}},\quad {\boldsymbol \Sigma }={\begin{pmatrix} 9 & 5 \\ 5 & 4 \end{pmatrix}}$$

For this exercise, and the rest of the chapter, the mean and the variance-covariance matrix will be preloaded for you as mu.sim and sigma.sim.

Generate 100 samples from the bivariate normal distribution and assign them to the object multnorm.sample.
Print the first six samples.
Create a scatter plot of the generated samples.
