Answer 1

t = (mean1 - mean2)/standard error (SE) of difference between means

SEdiff = √(SEmean1^2 + SEmean2^2)

SEm = SD/√(n-1)

Since only one SD can be calculated, you can use just that to determine SEdiff.

Consult your t-test table in the back of your stat book to determine the probability for df = 11.
