Which of the following statements is true? The 95% confidence interval is wider than the 99% confidence interval. The ONLY way to reduce the width of a confidence interval is to reduce the confidence level. The required sample size for a population mean is ONLY dependent on population variance. Given population variance and sampling error, higher confidence level results in larger sample size.
