Problem 2.32 (a) Use Minitab to produce the scatterplot, including the Regression line. |
|
(b) Comment on the strength of any association between Cycle-length and Day-length. |
|
(c) Carry out a regression on Cycle-length vs. Day-length. (Stat>Regression>Regression) |
|
(d) Explaining your answer carefully, use the value of R2 to decide whether this regression is useful. |
