3. Question 3 Aa Aa E A confidence interval estimate is an estimate of a population parameter providing an interval that is believed (with a certain level of confidence) to contain the value of the population parameter. The confidence level is the level of confidence associated with the confidence interval estimate. If your confidence level is 94%, then if you were to employ repeated sampling and compute the confidence interval estimate for each sample, you would expect % of the...

Constructing Confidence Intervals, Part 1: Estimating Proportion
Assume that a sample is used to estimate a population proportion p.
Find the margin of error E that corresponds to the given statistics
and confidence level: In a random sample of 200 college students,
110 had part-time jobs. Find the margin of error for the 98%
confidence interval used to estimate, for the entire population of
college students, the percentage who have part-time jobs. Round
your answer to three decimal places.
