[Lign251] HW4: Q3 c-ii

[Alex Del Giudice]

I'm having a hard time coming up with any intuitions regarding 
correlations and the statistical power of paired/unpaired t-tests.

I think this is because it seems to me that you can hold one constant 
and vary the others wildly (e.g. invent pairs of data sets that 
correlate very well but have drastically different results for p values 
of paired and unpaired t-tests - which is something I think I've done 
with the help of R).

Can anyone maybe give me a hint which may lead me to better intuitions?
