**MathGuru**, Wednesday, April 3, 2013 at 8:26pmYou'll need to start by finding a confidence interval for 2 samples.

Here is one you might be able to use:

CI = (mean difference) t-value (standard deviation difference/√n)

You will need to calculate the means and standard deviations.

T-value is found using a t-table for 98% confidence.

n = sample size

Once you have the interval calculated, you will have the lower and upper limits.
