Construct 90%, 95%, and 99% confidence intervals to estimate μ from the following data. State the point estimate. Assume the data come from a normally distributed population. 13.5 11.6 11.9 12.9 12.5 11.4 12.0 11.7 11.8 13.5 Appendix A Statistical Tables (Round the intermediate values to 4 decimal places. Round t values to 3 decimal places. Round your answers to 2 decimal places.)
Construct 90%, 95%, and 99% confidence
| 13.5 | 11.6 | 11.9 | 12.9 | 12.5 | 11.4 | 12.0 |
| 11.7 | 11.8 | 13.5 |
(Round the intermediate values to 4 decimal places. Round t values to 3 decimal places. Round your answers to 2 decimal places.)
90% confidence interval: enter the lower limit of the 90% confidence interval ≤ μ ≤ enter the upper limit of the 90% confidence interval
95% confidence interval: enter the lower limit of the 95% confidence interval ≤ μ ≤ enter the upper limit of the 95% confidence interval
99% confidence interval: enter the lower limit of the 99% confidence interval ≤ μ ≤ enter the upper limit of the 99% confidence interval
