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 12.5 12.5...

Construct 90%, 95%, and 99% confidence intervals to estimateμ from the following data. State the point estimate. Assume the data come from a normally distributed population.

(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


The point estimate is enter the point estimate  .
