The follow set of questions refer to the information below: March Madness is on! A researcher predicts that fans who played high school basketball will form better brackets (i.e., have more correct picks) than fans that did not play high school basketball. The researcher recruits ten fans, records whether they played high school basketball, and then has them complete a bracket for the first round of the tournament. She finds the following number of correct picks: Played high school basketball Didn't play high school basketball 12 6 8 10 4 14 12 14 12 8

Should you use a one-tailed or two-tailed test? (type in one OR two) What is the mean for individuals who played high school? What is the mean for individuals who didn't play in high school? What is the estimate of the population variance for those who played in high school? EX-M)? SS • (reminder: S, n- 1 n- 1 What is the estimate of the population variance for those who didn't play in high school? EX-M)? SS • (reminder: 5 n- 1 n- 1 What is the standard error (of the difference between means)? (remember to round to the second decimal place) s²1x (n1- 1)+s2x (n2 - 1) (n1- 1) + (n, – 1) 1 | | • (reminder: 5M1-M2 %3D n1 n2 | What is the t-value? (remember to round to the second decimal place) How many degrees of freedom are there? What is the critical value if alpha = .05? (remember, this depends on whether it is a one- vs. two-tailed test) What conclusion should you draw? (choose the appropriate letter (e.g., a, b, c, or d) based on the options below? a. Fail to reject the null because your results are statistically significant! b. Reject the null because your results are statistically significant! C. Fail to reject the null because your results are not significant :( d. Reject the null because our results are not significant :( What is the effect size (eta-squared)? (remember to round to the second decimal place) That's it! You did it!
