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...
