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 0.13. Each independently constructed a confidence interval based on the point​ estimate, but​ Jaime's interval has a lower bound of 0.092 and an upper bound of 0.205​, while​ Mariya's interval has a lower bound of 0.079 and an upper bound of 0.181. Which interval is​ wrong? Why?

Choose the correct answer below.

A. Jaime​'s interval is wrong because it is not centered on the point estimate.

B. Mariya​'s interval is wrong because it does not include the point estimate.

C. Jaime​'s interval is wrong because it is too wide.

D. Mariya​'s interval is wrong because it is too narrow
