**MathGuru**, Friday, March 19, 2010 at 9:29amCI95 = mean + or - 1.96(sd divided by √n)

...where + or - 1.96 represents the 95% confidence interval using a z-table, sd = standard deviation, √ = square root, and n = sample size.

Using your data:

CI95 = 130 + or - 1.96 (12/√36)

I'll let you finish the calculation to determine the interval.

I hope this will help.
