(Round your answer to two decimal places.)2--1.73xCalculate the z-score for the largest observation. (Round your answer to two decimal places.)2=2.05xAre there any unusually large or small observations?Since the 2-score for the larger observation is larger than 2 in absolute value, the larger value is unusually large.Since the 2-score for the smaller observation is larger than 2 in absolute value, the smaller value is unusually small.Since both 2-scores exceed 2 in absolute value, both of the observations are unusual.Since neither z-score exceeds 2 in absolute value, none of the observations are unusually small or large.

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 90% confident that the estimated percentage is in error by no more than one percentage point? Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage to be estimated. n= (Round up to the nearest integer.) b. Assume that a prior study conducted by an organization showed that 84% of women give birth. n= (Round up to the nearest integer.) 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…
