Based on the literature, the researcher knows that the mean test and class anxiety score of all graduate students is 3.45.The correct statistical test the researcher should conduct is [[1]]. The null hypothesis is that mean anxiety scores for graduate students at Statistics University is [[5]]. The alternative hypothesis is that the mean anxiety scores for graduate students at Statistics University is [[9]].After verifying that the assumptions for the test were met, the researcher ran the test and obtained the following output from SPSS:The results of the test were [[7]], t([[11]]) = [[10]], p = [[12]]. The standardized effect size was [[14]], indicating [[15]] practical significance.
