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.
12.5 | 11.6 | 11.9 | 12.4 | 12.5 | 11.4 | 12.0 |
11.7 | 11.8 | 12.5 |
(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 ≤_____
95% confidence interval: enter the lower limit of the 95%
confidence interval_____ ≤ μ ≤____
99% confidence interval: enter the lower limit of the 99%
confidence interval_____ ≤ μ ≤_____
The point estimate is_____
