Question 39 (7 points) For all hypothesis tests, one must (a) indicate Ho and H., (b) interpret whether to reject Ho or not reject Ho, and (c) indicate the effect size or explained variance. 5 bottles of beer are made to the subjects of an experimental group (group A) and 2 bottles to those of a control group (group B). We then measure their reaction time (the smaller the value, the faster their reaction time) to a light stimulation. Is the reaction time of group A significantly slower than that of group B (a = 0.05)? Group statistics Mean error band N Mean.
