wo Sample Z Hypothesis Tests is a parametric test is to compare the means of two independent groups of samples drawn from a normal population.

Single sample test of a given proportion is used to estimate the proportion of the population. It is used to compare the proportion to a target.

Two sample Z test of proportions is the test to determine whether the two populations differ significantly on specific characteristics.

One sample Z hypothesis test is one of the basic tests of inferential statistics. It is a parametric procedure for hypothesis testing.

Two Sample T tests are used to resolve hypothesis tests around comparing process means. The underlying chart makes use of the T distribution.
