Which of the following statement is INCORRECT about the reason for running a two-samples t-test instead of running a one-sample t-test?
O a. The control group may provide a baseline with which to compare the means of the experimental group
O b. In most real research projects, we do not have information about the parameters
O c. The two-samples t-test is methodologically more sound and valid than the one-sample counterpart
Od. We need to recruit a greater number of participants in order to increase the power of the study
