Two researchers, Jaime and Mariya, are each constructing confidence intervals for the proportion of a population who is left-
handed. They find the point estimate is 0.12. Each independently constructed a confidence interval based on the point estimate, but Jaime's interval has a lower bound of 0.078 and an upper bound of 0.193, while Mariya's interval has a lower bound of 0.051 and an upper bound of 0.189. Which interval is wrong? Why?
