In a study of students blanking out on tests, the arrangement of test items was studied for its effect on anxiety. The following scores are measures of "debilitating test anxiety" (based on data from "Item Arrangement, Cognitive Entry Characteristics, Sex and Test Anxiety as Predictors of Achievement in Examination Performance," by Klimko, Journal of Experimental Education, Vol. 52, No. 4.) Is there sufficient evidence to support the claim that the two samples are from populations with different medians? Is there sufficient evidence to support the claim that the arrangement of the test items has an effect on the score? Use a 0.01 significance level. 0 Questions Arranged from Easy to Difficult 24.64 39.29 16.32 32.83 28.02 33.31 20.60 21.13 26.69 28.90 26.43 24.23 7.10 32.86 21.06 28.89 28.71 31.73 30.02 21.96 25.49 38.81 27.85 30.29 30.72 Questions Arranged from Difficult to Easy 33.62 34.02 26.63 30.26 35.91 26.68 29.49 35.32 27.24 32.34 29.34 33.53 27.62 42.91 30.20 32.54
