The t-test is commonly used for making inferences about the means of parent populations when the standard deviation of the population is unknown and the sample size is small. It is applicable for two-group comparisons, and typically involves comparing the means of two samples to determine if they are significantly different from each other. The F-test is also used for comparing means, but it is typically used in ANOVA (analysis of variance) to determine if there is a difference between the means of three or more groups. The p-test and z-test are not commonly used terms in statistics. The chi-square test is typically used for testing the association between categorical variables.
