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. 13.4 11.6 11.9 13.0 12.5
11.4 12.0
11.7 11.8 13.4

(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
11.817
≤ μ ≤ enter the upper limit of the 90% confidence interval

95% confidence interval: enter the lower limit of the 95% confidence interval
11.737
≤ 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
