Wider margin of error No change in margin of error Narrower margin of error Cannot be determined without knowing the precise data. All changes saved 4. Believing that their data needs to be more accurate, the researchers from Question 1 survey 300 more adult females for a total of 681 adult females but find their mean is unchanged at 65.2 inches with a standard deviation that has dropped to 1.9 inches. Construct a confidence interval with the same confidence level but with the new sample size and standard deviation. O (65.08, 65.32) (65.06, 65.34) O (64.88, 65.52) O (64.98, 65.41)
