Scenario 2 The following table is derived from the Banerjee et al (2010) study on vaccination rates in India. Control Group Treatment Only Treatment plus Incentive Children not fully immunised 234 810 50 311 68 Children fully immunised 148 12. Refer to Scenario 2. What is the point estimate of the proportion of children that were fully immu- nised in villages that received only the treatment and not the additional incentives? A) 0.613 B) 0.219 C) 0.179 D) 0.821 E) 0.387 13. Refer to Scenario 2. Suppose a researcher wants to test the null hypothesis that the true proportion of children that were fully immunised in villages that received only the treatment was exactly 0.2 at a 99% level of significance. What critical value will the researcher have to look up in the appropriate statistical table in order to do this? A) 1.28 B) 1.645 C) 1.96 D) 2.33 E) 2.575
