Study participants are vaccinated and are observed for 24 weeks. At the conclusion of the study, the researchers conclude with 95% confidence that the vaccine is 90% effective, with a margin of error of 0.3% Part A: Which statement most accurately explains the researchers' conclusion? Part B: What conclusion can you draw from the size of the margin of error in this study? Select one aniswer for Part A and one answer for Part B. A. The researchers are saying that the vaccine will be 95% effective in 94% of all duplicate studies. A: The researchers are saying that if the study was repeated several times, 95% of those studies would find the vaccine between 93.7% and 94.3% effective. 8: The margin of error in this study is relatively high which means that the statistic calculated by the researchers is very similar to the true parameter B: The margin of error in this study is relatively low, which means that the statistic calculated by the researchers is very similar to the true parameter B: The margin of error in this study is relatively high, which means that the statistic calculated by the researchers is not very similar to the true parameter. A: The researchers are saying that if the study was repeated several times, between 94.7% and 95.3% of those studies would find the vaccine 94% effective. Gi B: The margin of error in this study is relatively low which means that the statistic calculated by the researchers is not very similar to the true parameter. A: The researchers are saying that the vaccine is between 93.7% and 94.3% effective, and they are 95% confident that the study was not biased e to search
