The original sample size (before doubling it) is 1,000. 70% of people agree with the survey, 16% disagree, and 13% are undecided. The margin error is +/- 3%. There is a 95% confidence level.

o Using the sample proportion and the margin of error, provide the confidence interval estimate of the true population proportion. . Now double the sample size, but keep the sample proportion the same. Assuming a 95% confidence level, calculate the new margin of error and the new confidence interval. Then describe how the confidence interval changes when the sample size gets larger. Show your calculations below
