Identify the distribution

Below is a scatterplot of 1000 samples from three bivariate distributions with the same location parameter and variance-covariance matrix:

• A multivariate t with 4 degrees of freedom (T4)
• A multivariate t with 8 degrees of freedom (T8)
• A multivariate normal (Normal)

What is the correct match of the above distributions to Samples 1 through 3?
