9. A sample of n = 3 were asked to participate in a cognitive task to evaluate analytic versus holistic perception. Participants were asked to view a computer screen that displayed a scene with several items (fecal and background). Participants viewed the screen for 30 seconds and were then asked to recall as many items as they could. After a 10 minute rest period, participants were asked to view the same scene but the background color had been changed. The experiment was repeated. Using the data below, and a .05 level of signicance determine whether changing the background impact participant recall. a. Provide the hypotheses for this study. b. What is the df value for this study and the critical boundary using 2-tailed o: = .05? c. What is the (1) pooled variance, (2) standard error of the mean, and (3) t-statistic
