25 2.5 points Which statement is not true about confidence intervals? $ 000 An approximate formula for a 95% confidence interval is the sample statistics +/-2(standard error of the statistic). A confidence interval is an interval of values computed from sample data that is likely to include the true population value. If we consider all possible randomly selected samples of the same size from a population, the 95% is the percentage of those samples for which the confidence interval includes the population parameter. A confidence interval between 20% and 40% means that the population proportion lies between 20% and 40%. Previous Next
