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 0.09. Each independently constructed a confidence interval based on the point estimate, but Jaime's interval has a lower bound of 0.061 and an<br>upper bound of 0.119, while Mariya's interval has a lower bound of 0.034 and an upper bound of 0.168. Which interval is wrong? Why?<br>Choose the correct answer below.<br>O A. Jaime's interval is wrong because it does not include the point estimate.<br>O B. Mariya's interval is wrong because it is not centered on the point estimate.<br>O C. Jaime's interval is wrong because it is too narrow<br>O D. Mariya's interval is wrong because it is too wide.<br>
