Tests the difference between two means when the standard deviations of the two populations are known. The
normal distribution is used for the 2-Sample

Tests a single sample proportion against the known proportion of the null hypothesis. The normal distribution is
used for the 1-Proportion

Test .... [Test] - [Two-Prop Z-Test] .....
Tests the difference between two sample proportions. The normal distribution is used for the 2-Proportion
test.
