I understand everything about hypothesis testing. I am not clear about the preconditions being met.
"the mean value is far enough from zero so that it can't be just a natural fluctuation"
A natural fluctuation of what? Of the trend? Do we conclude "b" is nonzero? I think we will only find out whether the hypothesis that the function is linear of some b must be rejected.
