The following situation is presented, in each one, you will identify 

(1) the type of study (observational, quasi-experimental, or experimental), (2) the experimental unit, (3) factors and their levels (if any), (4 ) response, (5) treatment design, (6) type of experimental design (completely randomized, randomized blocks, factorial experiment, independent samples, etc.), (7) alternate hypothesis, and (8) test statistics to use.
