A) All statistical tests of inference produce a p-value, which indicates the probability of obtaining the observed (or more extreme) results if the null hypothesis is true.
B) Statistical tests of inference provide information about how safe it is to reject the null hypothesis. Specifically, the significance level (usually set at 0.05) determines the probability of erroneously rejecting the null hypothesis (type I error).
C) Different statistical tests are designed for use under different conditions, such as the type of data being analyzed and the research question being addressed. For example, t-tests are used to compare means between two groups, while ANOVA is used for comparing means between more than two groups.
