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

13.311.611.912.612.5

11.412.011.711.813.3

(Round standard deviation to 4 decimal places, e.g. 25.3172. Round your answers to 2 decimal places, e.g. 25.31.)

90% confidence interval:

enter an appropriate value rounded to 2 decimal places

enter an appropriate value rounded to 2 decimal places

95% confidence interval:

enter an appropriate value rounded to 2 decimal places

enter an appropriate value rounded to 2 decimal places

99% confidence interval:

enter an appropriate value rounded to 2 decimal places

enter an appropriate value rounded to 2 decimal places

The point estimate is
