(b) Test whether rainfall affects yield for each of the phases of the wheat growing season. Be sure to do all parts of the hypothesis tests and carefully report your findings. (c) Now test whether rainfall as a whole affects yield. Be sure to do all parts of the hypothesis test, and carefully report your results. How does your test differ from what you did in part (b)? Did your results change? (d) It should be obvious that several vanables other than rainfall affect crop yield. Use a RESET test to explore whether our model may be inadequate in some important way. Be sure to do all parts of the hypothesis test. What do the RESET results suggest to you!
