AP STATS Linear Regression Classwork Answers

Classwork Answers (1-5) 1.R 2 = 48.2% 2.Differences in fares explain 48.2% of the variability in distance. 3.b 1 =.0786 4.b 0 = 177.21 5.fare-hat = 177.21 + 0.0786 (distance)

Classwork Answers (6-10) 6.The predicted fare for a 200-mile flight is \$192.93 7.The predicted fare for a 2000-mile flight is \$334.41. 8.I will explain… 9.The fare is \$177.21 when the distance is zero. This is the base fare. 10.For each additional mile flown, the fare increases by \$0.0786.

Classwork Answers (11-13) 11.The residual is the actual fare minus the predicted fare. The actual fare is \$212 and the predicted fare (y-hat) is \$312.32. The residual is \$-100.32. 12.A positive residual means that the actual fare is more than the predicted fare. 13.A negative residual means that the actual fare is less than the predicted fare.
