In this R script, we demonstrate the distribution of the sample average of an exponentially distributed random variable resembles the normal distribution.

In this R script, we test to see if a continuously distributed random variable is normally distributed. Typically, empirical observations need not follow a specific distribution, so we need to conduct statistical test to see what is the most likely distribution. Experimentally, we sample from an exponential and normal distribution and perform the Shapiro-Wilk test (useful for low samples - KS test for large samples) to test for normality.
