How do I find the best point of estimate for 2 samples?

Here is my data:

A: 78, 84, 81, 78, 76, 83, 79, 75, 85, 81

B: 85, 75, 83, 87, 80, 79, 88, 94, 87, 82

$\displaystyle \bar{x}$A = 80

S = 3.367

N = 10

$\displaystyle \bar{x}$B = 84

S = 5.395

N = 10

Reading my notes it sounds like 80 would be the best point of estimate for A and 84 the BPA for B, I think? Would the BPA for both be 82?

Thanks for the help
