5 Alexa believes that students are equally likely to achieve the same percentage score on each of two tests, paper I and paper II. She randomly selects 8 students and gives them each paper I and paper II. The percentage scores for each paper are recorded.
The following paired data are collected.
| Student | \(A\) | \(B\) | \(C\) | \(D\) | \(E\) | \(F\) | \(G\) | \(H\) |
| Paper I (\%) | 70 | 70 | 84 | 80 | 64 | 65 | 65 | 90 |
| Paper II (\%) | 64 | 76 | 72 | 74 | 68 | 64 | 58 | 76 |
Test, at the \(1 \%\) significance level, whether or not there is evidence to support Alexa's belief. State your hypotheses clearly and show your working.
