Tо test а new vаccine designed tо prevent children cоntrаcting a virus, researchers randomly assigned 2,000 children to one of two groups. The first group, 1,000 of the children received the new vaccine, while the second group, contained 1,000 children were given a placebo. Of the children who received the vaccine, 30 contracted the virus. Of the children who received the placebo, 45 contracted the virus. Is there sufficient evidence to conclude that the use of new vaccine leads to a true proportion of children who will contract the virus that is lower than for those given the placebo? Conduct the test at the 0.05 significance level. State the null and alternative for this situation.
