Question

An instructor wished to determine whether providing a bilingual dictionary to students with limited English proficiency improves science test scores. A small class of students (n = 10) was chosen. Students were given two science tests.
Each test covered the same type of science content; however, students were given a bilingual dictionary on the second test. The information in the table speaks to the students' performance on every science test.
Use a one-tailed Wilcoxon signed ranks test with α = 0.05 to determine which testing condition brought in higher scores. Report your findings.
