The appropriate chi-square test for this scenario is the goodness-of-fit test, as it allows us to determine whether the observed distribution of verdicts differs significantly from what would be expected by chance. The other options (association, dissociation, and independence) are not appropriate for this situation as they are designed for testing relationships between variables.
