Using correlational research, if there are 20 adopted females given a shyness test of 0-20 (higher the score, the more the shyness), and the 20 adopted mothers and 20 biological mothers were tested...

What might be the correlational coefficients for

a) shyness is partially inherited, if shyness is inherited 1)what is the correlation between daughter and biological mothers test? 2)correlation between daughter and adoptive mothers

AND

b) if shyness is environmental 1)what is the correlation between daughter and biological mothers and 2)correlation between daughter and adoptive mothers

There should be 2 values for a) and 2 for b)

How to go about doing this?
