What is the critical value? What is the obtained value for your hypothesis test? Should we reject or fail to reject the null hypothesis? What is your calculated effect size? What is the coefficient of determination that describes the relationship between time (pre test vs post test) and recall? What does this coefficient of determination mean?

31 Points A developmental psychologist predicts that seven-year-old children who are trained to use a particular memory strategy will recall significantly more words (from a list of 20 words), on average, than they would recall before learning the strategy. She tests her hypothesis with 10 randomly selected children, whose pre- and post-training recall scores are as follows: P01 P02 P03 P04 P05 P06 P07 P08 POP PID 8 5 5 6 8 7 Pre 12 6 11 8 10 13 14 (assume alpha=0.05)?
