Question

To the right is a regression analysis of and nicotine content of cigarettes. Use the information to answer parts a through e below. What does intercept mean? The model predicts that a far-free cigarette would have b_1 milligrams of nicotine. The model predicts that a cigarette with no nicotine would have b_1 milligrams of tar. The model predicts that a far-free cigarette would have b_0 milligrams of nicotine. The model predicts that a cigarette with no nicotine would have b_0 milligrams of tar. If a new brand of cigarette contains 11.07 milligrams of tar and a nicotine level whose residual is 2.0 mg, what is the nicotine These cigarettes have a nicotine content of milligrams. (Round to three decimal places as needed.)

Explanation / Answer

Residual ei = 0.2

Regression equation,

Nicotine content= 0.672 + 0.041*Tar + ei

When tar = 11.07 then ,

Nicotine content = 0.672 + 0.041*11.07 + 0.2

= 1.326mg
