"Conduct hypotheses tests at a 5% significance level on the intercept and slope coefficient to see if the intercept is significantly different from zero and the slope coefficient is significantly different from one "

Does this mean i have 2 different hypotheses tests, or 1 that compares both? As i've carried out a hypothesis on the slope coefficient

Null: H0: β1 = 0 at  = 0.05
Alt: H1: β1 ≠ 0 at  = 0.05
Test-stat = 5.309772708
Critical value = maybe 2.042
T is smaller Than C so Reject H0

Any pointers on this would be great as im trying to pick up the basics but am stuck on this part of my online course

  • $\begingroup$ The question indeed is ambiguous and could mean either one of your interpretations. If your answer will be used to evaluate your performance in a course or job, then consider responding to both interpretations. The use of plural in "hypotheses tests" suggests two tests are requested--but that still leaves open the question whether the "5% level" should be applied to each test separately or to the combined result. $\endgroup$ – whuber Mar 9 '18 at 15:39
  • $\begingroup$ Yes, i'm thinking its two different tests, both with a 5% significant test. But i shall play it safe and try do it both ways as suggested $\endgroup$ – user198158 Mar 9 '18 at 15:43
