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.
13.2 | 11.6 | 11.9 | 12.5 | 12.5 | 11.4 | 12.0 |
11.7 | 11.8 | 13.2 |

(Round the intermediate values to 4 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
