Well, you lazy bums. I suppose you're too busy on MySpace to e-mail me any answers, so here's a few:
17c) First take the squareroot of 0.924. I forget exactly what this is, but it is 0.9something. This tells us there is a strong, positive, linear relationship between tar and nicotine.
17d) For every 1 more mg of tar, we predict about 0.065 more mg of nicotine.
17e) Even with no tar, we still predict about 0.154 mg of nicotine.
1d) 92.3% of the variation in age can be explained by the regression on age.
1f) She is shorter than predicted, for her age.
1g) Wait until next week.
See you in the morning!
Now go to bed! :o)
