a. Explanation The vaccine is tested with 500 volunteers in a village who are malaria free at the beginning of the trial. In which 200 of the volunteers will get the experimental vaccine and the rest will not be vaccinated. The chance of contracting malaria is 10% for those who are not vaccinated. The number of volunteers who are not vaccinated and have malaria is calculated below: ( Number of volunteers who are not vaccinated have no malaria ) = 300 − 300 × 10 100 = 300 − 30 = 270 Thus, the number of volunteers who are not vaccinated and have malaria is 270. Here, the vaccine has no effect. Therefore, the chance of contracting malaria is also 10% for those who are vaccinated b. To determine Construct a two-way table to show the results of the experiment if the vaccine cuts the risk of contracting malaria in half.
