An epidemiologist plans to conduct a survey to estimate the percentage of women who give birth. How many women must be surveyed in order to be 99% confident that the estimated percentage is in error by no more than two percentage points? Complete parts (a) through (c) below. Question content area bottom Part 1 a. Assume that nothing is known about the percentage to be estimated. n=enter your response here (Round up to the nearest integer.) Part 2 b. Assume that a prior study conducted by an organization showed that 81% of women give birth. n=enter your response here (Round up to the nearest integer.) Part 3 c. What is wrong with surveying randomly selected adult women? A. Randomly selecting adult women would result in an overestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have completed the time during which they can give birth. B. Randomly selecting adult women would result in an underestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have already given birth. C. Randomly selecting adult women would result in an overestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have already given birth. D. Randomly selecting adult women would result in an underestimate, because some women will give birth to their first child after the survey was conducted. It will be important to survey women who have completed the time during which they can give birth.
