**Natasha**, Thursday, June 24, 2010 at 7:01pmA confidence interval for the mean is a range ìlower < ì <ìupper where the lower bound is the smallest value of ì that we expect and the upper bound is the largest value of ì that we expect”(Doane-Seward,2007).

“If we wanted a narrower interval(i.e. more precision) we could either increase the sample size or lower the confidence level.”
