It is used for comparison of more than two grop means

2) (1) (CHI-SQUARED)

Independent of attributes is one of the appliction of chisquare test

3) (3) ( Gaussian for the proportion or difference of two proportions)

Here testing proportion(s). So we use Z-test for proportion(s)

4) (2) (Gaussian for the mean or difference of means)

It is a quantitative data and also testing the numerical response. So we use Z-test for mean(s).

5) (4) ( t-test for the mean or difference between means)
