Univariate Gaussians or normal distributions have a simple representation in that they can be completely described by their mean and variance. These distributions are particularly useful because of the central limit theorem, which posits that when a large number of independent random variables are added, the distribution of their sum is approximated by a normal distribution. In other words, normal distributions can be applied to most problems Recall the probability density function of the Univariate Gaussian with mean and variance...

Suppose that Vera wants to test the hypothesis that women make less money than men doing the same job. According to the Bureau of Labor Statistics (BLS), the median weekly earnings for men in the sales and office occupation sector in 2015 was $704. Vera collected median weekly earnings data for women in 2015 from a random subset of 18 positions in the sales and office occupation sector. The following is the sample data. S627, 5617, S732, S735, $639, S569,...
