Questions 14-24. A study of the effects of color on easing anxiety compare anxiety test scores of participants who completed the test printed on either soft yellow paper or on harsh green paper. The scores for the five participants who completed the test on yellow paper are 17, 19, 28, 21, and 18. The scores for the four participants who completed the test on green paper are 20, 26, 17, and 24. Using the .05 significance level, determine if anxiety scores are lower for those who complete the test on soft yellow paper compared to those who complete the test on harsh green paper. M1 = 20.60; SS1 = 77.20 M2 = 21.75; SS2 = 48.75 Group 1= soft yellow paper; Group 2 = harsh green paper

14. What is the null hypothesis? a. Those who draw on green paper and those who draw on yellow paper will have the same anxiety scores b. Those who draw on yellow paper will have higher anxiety scores than those who draw on green paper c. Those who draw on yellow paper will have lower anxiety scores than those who draw on green paper d. Those who draw on yellow paper will have different anxiety scores than those who draw on green paper

15. What is the research hypothesis? a. Those who draw on green paper and those who draw on yellow paper will have the same anxiety scores b. Those who draw on yellow paper will have higher anxiety scores than those who draw on green paper c. Those who draw on yellow paper will have lower anxiety scores than those who draw on green paper d. Those who draw on yellow paper will have different anxiety scores than those who draw on green paper

16. What is the comparison mean? a. 0 b. 20.60 c. 21.18 d. 21.75

17. What is the comparison standard deviation? a. 0 b. 1.96 c. 2 d. 2.85

18. Explain how you calculated the comparison standard deviation. Detail the process (i.e., the steps) in calculating this statistic. Do not just list equations. In your explanation, be sure to use the names of the concepts. For example, if you are calculating a deviation score, use that specific term. Do not simply say "that number."

19. What is/are the cutoff(s)? a. 2.262 b. 2.365 c. -1.833 d. -1.895

20. What is the t-score for the sample score? a. -0.02 b. -0.40 c. -0.58 d. -0.59

21. Upload your work for the hand calculations for the comparison standard deviation and the t-score for the sample score. Be sure to show ALL of your work.

22. Upload a sketch for this hypothesis test labeling: a) the cutoff(s) b) the rejection region(s) c) and the sample t-score

23. What is your conclusion for this hypothesis test? a. reject the null b. accept the research hypothesis c. accept the null d. fail to reject the null
