20 Notice that for 20 = 100% of the samples, the 95% confidence interval contains the population mean. Choose the correct statement. When constructing 95% confidence intervals for 20 samples of the same size from the population, at least 95% of the samples will contain the population mean. When constructing 95% confidence intervals for 20 samples of the same size from the population, exactly 95% of the samples must contain the population mean. There must have been an error with the way our samples were chosen. When constructing 95% confidence intervals for 20 samples of the same size from the population, the percentage of the samples that contain the population mean should be close to 95%, but it may not be exactly 95%
