A study of the effects of color on easing anxiety compared anxiety test scores of participants who completed the test printed on either soft yellow paper or harsh green paper. The researcher predicted that the yellow paper would produce lower anxiety scores than the green paper. The scores for the five participants who completed the test printed on the yellow paper were: 17, 19, 28, 21, 18. The scores for the four participants who completed the test of the green paper were: 20, 26, 17, 24.Using the .05 significance level, and selecting an appropriate test (one or two tailed),what should the researcher conclude? Should they accept or reject the null hypothesis?Submit an Excel document that includes all of your calculations, as well as a Word document that includes responses to the following items:a) What are the researcher’s null and research hypotheses?b) What is the cut-off value(s) that marks where the critical region is?c) What are the degrees of freedom for the hypothesis test?d) What is the value of the test statistic? (i. e., your t or z value)e) Based on your test statistic, what decision should the researcher about their hypotheses
