You can put this solution on YOUR website! The following is a set of data that represent a sample from a population X. Build a confidence interval for the population mean with 90% confidence interval.
The data are:
22,25,27,24,29,20,12,43,13,21,35.
-------
x-bar = 24.64
std = 8.98
------
ME = 1.645*8.98/sqrt(11) = 4.45
-----
90% CI:: 24.64-4.45 < u < 24.64+4.45
