Answer #1

d. Wilcox on matched pairs test

Explanation:

For the related samples, we use either paired t test or Wilcoxon sign rank test. We cannot use independent t test, because samples are not independent and scale of data is not ratio. For the given data, it is explained that data set contains ordinal data, so we cannot use the parametric test for related samples, that is, we cannot use paired t test. So, corresponding non-parametric test for related samples is Wilcox on matched pairs test
