Nine software engineers were interviewed to develop an estimate for software lines of code. The mean estimate is 12480 lines of code with a standard deviation of 2400 lines of code. Develop an 90% confidence interval for the population mean.
-----
sample mean:: x-bar = 12480
Margin of Error:: ME = 1.645*2400/sqrt(9) = 1315.88
------
90% CI:: 12480-1315.88 < u < 12480+1315.88
