Do i understand correctly that for one sided t-tests with regression
coeficcients, I do the following (H0:c=0, Ha: C<0):
a)check if the coefficient is negative
b) divide the pvalue by 2.
Reject null if p value is significant or if coefficient is positive.
Do NOT reject the null if the coefficient is positive, as the estimated C
is obviously not less than 0. The null can be thought of as being
equivalent to H0: c>=0.
