Elementary Statistics (12th Edition)

First we put each data set into Microsoft Excel. Then, using Excel, we find that the first population has $43.8\lt μ\lt50.1$ and the second population has $42.6\lt μ \lt46.4$. The two values overlap, hence we can see that it is possible (but not $100\%$) that the populations have the same mean, meaning that discrimination possibly is not present.
