Compute the average amount a supporter donates under each variant. Do your analysis separately for each party. For any party, are thre any variants statistically better than variant 1 at the 5% level? If so, report the p-value associated with the test of the best-performing variant. For our purposes, this is the variant that outperforms variant 1 by the greatest donation margin). Report your answer in PERCENTAGE FORM (decimal form multiplied by 100).
