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 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 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 What is the comparison mean? a. 0 b. 20.60 c. 21.18 d. 21.75 What is the comparison standard deviation? a. 0 b. 1.96 c. 2 d. 2.85 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." What is/are the cutoff(s)? a. 2.262 b. 2.365 c. -1.833 d. -1.89

What is the t-score for the sample score? a. -0.02 b. -0.40 c. -0.58 d. -0.59 Upload work for the hand calculations for the comparison standard deviation and the t-score for the sample score.

Upload a sketch for this hypothesis test labeling: a) the cutoff(s) b) the rejection region(s) c) and the sample t-score 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 24. Provide an interpretation of your findings and the report of the statistics for this hypothesis test. An interpretation is a one-sentence conclusion of the hypothesis test.
