Sampling a Gaussian distribution

When we face a problem where we are provided with samples from probability distributions and we want to recover their parameters, we need to estimate them. When the samples come from only one distribution, the estimation is usually straightforward.

Gaussian distributions are really useful in understanding the main properties of probability distributions. In this exercise, you will learn (1) how to create a sample from this distribution, (2) how to estimate its parameters if you were only provided with the data and (3) how to visualize the estimated distribution.

  • Simulate 500 samples from a Gaussian distribution with a mean of 5 and a standard deviation of 4 using the function rnorm(). Save the results into the object simulation.
  • Check the first six values with head()
