The df for the F-test is given in your results as 3 and 86. Number of
strata minus 1 ans number of PSUs minus 4. I'm not certain about the
t-tests.

Hi All,
I'm trying to figure out how to compute the df for t and F in these
results (below). I'm not sure what is being used as N? Any direction
would be helpful.
Thanks,
Jade
