The margin of error for a confidence interval depends on the
confidence level, the standard deviation, and the sample size. Fix
the confidence level at 95% and the sample standard deviation at 1
to examine the effect of the sample size. Find the margin of error
for sample sizes of 5 to 100 by 5's -- that is, let n = 5, 10, 15,
..., 100. (Round your answers to three decimal places.)
