Use a feature of the calculator to test the hypothesis. Indicate the feature used and the results: Use 1-Prop-Z-Test and get the same values shown in the work below. Test statistic = (see chapter 7.3) p-value = P(p-hat > .52) = P(z > 2.55) = 1 – .9946 = .0054 < .05 (significance level)

This was found using calculator (1-Prop Z ; test) Step 4: If the null hypothesis was true is unlikely we would see an infection rate as low as : 11 745 =0.0128 ( p ) so we conclude that the null hypothesis is mostly likely not true. So we reject the null hypothesis and conclude that the drug will reduce the number of cases.
