Hi
15 bags of pretzels off the assembly line and weighed their contents. 
If the sample mean is 10.0 and the sample standard deviation is 0.15
find the 95% confidence interval estimate for the true mean weight of bags 
ME = {{{ 2.14(.15/sqrt(15))}}} = .08
10 - .08 < {{{mu}}} < 10 + .08
9.92 < {{{mu}}} < 10.08
