Question 14 2.0 points possible (graded, results hidden) Say a training intervention is randomly assigned to a subset of unemployed individuals (treated) and not to others (control). The intention is to provide unemployed individuals with new skills so that they can get higher wages upon returning to the job market. The two groups are ex-ante identical and the sample size is 100,000 which is large enough for a normal approximation to be appropriate. The average earnings of the treated group is 1000 and the average earnings of the control group is 950. The variance of the difference between the treated and control groups is 25 and the 95% critical value for normal approximation is 2. Suppose the 95% confidence interval of the effect of the scholarship on student performance is (A, B). What is the value of A? What is the value of B? Can we reject the null hypothesis that there was no effect with 95% confidence? Yes Ο Ο No
