Answer Happy

Conditions Country Music (CW: Whiskey River), Classic Rock (R: Hotel California), or No Music (NM). Thirty-Three college students participated. Eleven participants were randomly assigned to study while listening to Country Music for 2 hours, a different 11 students were randomly assigned to study while listening e Classic Rock for 2 hours, and a different 11 students were randomly assigned to study while listening to No Music for 2 hours. The data are presented below. The researcher wants to maximize the Power of the test. Note: M = Mean, SS = Sum of Squares, N = Number in Condition, P = People (X- Ş CW ) (X- M M2 R ( XM) Mean People NM (X-M) (X-M) M2 1 82 -1 1 83 2 4 81 N 4 82 2 84 1 1 84 3 9 81 2. 2 4 83 3 83 O 0 o 82 1 1 81 2 4 82 4 85 4 83 2 2 4 78 -1 1 82 5 87 2. 4 3 4 16 84 3 9 81 2 4 84 6 86 82 1 1 78 - 1 1 82 9 4 7 85 N 80 -1 1 78 - 1 1 81 8 82 -1 1 78 -3 9 9 80 1 1 80 9 9 78 -5 25 79 -2 4 4 80 1 1 79 10 80 -3 9 77 -4 16 80 1 1 79 11 81 -2 4 72 -2 4 71 -8 64 ZZ X-83 X= 81 X- 79 GM= 81 SS- 74 SS 62 SS- 86

Question 19 If appropriate, conduct post-hoc analysis using Tukey's HSD. What is the critical value? (Input same number of decimal places as presented in Table) Question 20 If appropriate, what is the value of Tukey's HSD for comparing Country to Classic Rock? Note: If appropriate to calculate, Round answer to 2 decimal places. If not appropriate to calculate, input 999 2.44

Question 31 8 pts What is the value of the observed test statistic (t) used to determine whether, in the population, this relationship is significantly different from zero? (Round answer to 2 decimal places) Question 32 2 pts Assuming that you want to maximize the power of the test, what is the critical value used to compare the observed test statistic (t) in order to determine whether, in the Population, the relationship is significantly different from zero? (Input same number of decimal places as presented in Table) 2.093
