A one-sample z-test was used to test the following hypotheses: Ho: p = 13 and 1:13. Select the pair of 95% and 99% confidence intervals (which were based on the z-test) that are consistent with the following conclusion: 'There is moderate, but not strong, evidence against the null hypothesis. In fact the population mean appears to be less than 13. Select one: The 95% confidence interval is (20.4, 43.8) and the 99% confidence interval is (16.6, 47.6). The 95% confidence interval is (14.1, 37.7) and the 99% confidence interval is (10.4, 41.4). The 95% confidence interval is (-16.8, 6.8) and the 99% confidence interval is (-20.5, 10.5). The 95% confidence interval is (-1.8, 21.8) and the 99% confidence interval is (-5.5, 25.5). The 95% confidence interval is (-12.5, 10.9) and the 99% confidence interval is (-16.3, 14.7).
