20. Blanking Out on Tests Many students have had the unpleasant experience of panick- ing on a test because the first question was exceptionally difficult. The arrangement of test items was studied for its effect on anxiety. The following scores are measures of "debilitating test anxiety," which most of us call panic or blanking out (based on data from "Item Arrange- ment, Cognitive Entry Characteristics, Sex and Test Anxiety as Predictors of Achievement in Examination Performance," by Klimko, Journal of Experimental Education, Vol. 52, No. 4.)
A)Is there sufficient evidence to support the claim that the two populations of scores have different means?
B)Is there sufficient evidence to support the claim that the arrangement of the test items has an effect on the score?
C)Is the conclusion affected by whether the significance level is 0.05 or 0.01?
