The t test is the most appropriate statistical test for comparing the mean cholesterol levels between two groups (vegetarians vs. nonvegetarians). Chi-square test is used for categorical data, analysis of variance is used for comparing means between more than two groups, and Pearson correlation is used to determine the relationship between two continuous variables.
