1. c) Irienpret the recaring of the slope of the regressicn line y^b0+b1x in this contexd. A. For each
acditional milligram of nicotine, the mocel predicts a decrease of b1 miligrams of tar. B. For each
additional rrilligram of tar, the model predicls an increase of b1 milligrams of nicotine. C. For each
acditional milligram of tar, the model predicts a decrease b1 milligams of ricotine. d) What does
the intercept mean? A. The model precticts that a tar-free cigarette woukt have b1 miligrams of
nicotine. B. The model precicts that a tar-free cigarette would have b miligrams of nicotine. c. The
rodel predicis that a cigareite with ro nicotine would have b0 rilligramis of lar. D. The model
