I am having a problem finding my sample size through power analysis. I understand what power is but am unable to figure out what my power would be for the following information.

My population size consists of 6,866 subjects
my desired margin of error should be .80
I would like a 95% confidence level for this population.
I am using multiple regression to measure the extent of the relationship between the IV (14) and DV (1)

I need the formula to compute power for sample size, and also how to compute the answer, as well as the anwser.

Thanks for your assistance, Maddy
