Question

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. 12.0 11.6 11.9 12.9 12.5 11.4 12.0 11.7 11.8 12.0 Appendix A Statistical Tables (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 of the 99% confidence interval The point estimate is enter the point estimate .
