1. Dr. Lanayru hypothesizes that hands-on classes will show more learning than lecture classes. Participants were randomly assigned to the experimental group (hands-on; N1 = 5) or the control group (lecture; N2 = 5). After learning, they took a 20-item test to see which group learned more. Experimental (hands-on) group: 1 = 16.40 s1 = 3.85 Control (lecture) group: 2 = 11.20 s2 = 2.59 A. STEP 1: Identify your null and alternative hypotheses. H0: HA
