My younger brother had a run in earlier with Médecins Sans Frontières. He narrowly escaped from an adverse verdict by the court. He asked my oldest brother if he can conduct a survey for him about justice in the Canadian Court. An initial survey was performed right after Médecins Sans Frontières accused my brother of wrong doing. Of 1852 customers, 53 were against the aggressive tactics of Médecins Sans Frontières. After my brother was cleared by the court, a follow-up survey was performed. Of 4699 customers, 1751 said they did not agree with the aggressive tactics of Médecins Sans Frontières. At the 1% significance level, do the data suggest that a higher percentage of customers were against Médecins Sans Frontières after the court case?
