Test used to compare two means
Means of 3 or more variables

A) T-test, ANOVA
B) Chi-square test, Paired t-test
C) Z-test, Regression analysis
D) Mann-Whitney U test, Kruskal-Wallis test

Answer 1

The test used to compare two proportions is the Chi-square test, the test used to compare two means is the T-test, and the test used to compare the means of 3 or more variables is the ANOVA.

Step-by-step explanation:

The test used to compare two proportions is the
Chi-square test. This test is used when comparing the proportions of two groups or populations to determine if there is a significant difference between them. It measures the association between two categorical variables.

The test used to compare two means is the
T-test. This test is used when comparing the means of two groups or populations to determine if there is a significant difference between them. It measures the difference in means between two independent groups.

The test used to compare the means of 3 or more variables is the
ANOVA (Analysis of Variance). This test is used when comparing the means of 3 or more groups or populations to determine if there is a significant difference between them. It measures the variability among the means.
