Question

a.) Two variables are defined, a regression equation is given, and one data point is given.

	BAC	=	blood alcohol content ( % of alcohol in the blood)
	Drinks	=	number of alcoholic drinks
	^ BAC = -0.0124+0.019(Drinks_

The data point is an individual who consumed 3 drinks and had a BAC of 0.08.

Find the predicted value for the data point and compute the residual.   Enter the exact answers.

Predicted value =

Residual =

b.) Two variables are defined, a regression equation is given, and one data point is given.

	Weight	=	maximum weight capable of bench pressing (pounds)
	Training	=	number of hours spent lifting weights a week
	^ Weight = 100+11.9 (Training)

The data point is an individual who trains 5 hours a week and can bench 150 pounds.

Find the predicted value for the data point and compute the residual. Enter the exact answers.

Predicted value =   lbs

Residual =   lbs

c.) Two variables are defined, a regression equation is given, and one data point is given.

	Study	=	number of hours spent studying for an exam
	Grade	=	grade on the exam
	^ Grade = 40.6+3.9(Study)

The data point is a student who studied 10 hours and received an 81 on the exam.

Find the predicted value for the data point and compute the residual. Enter the exact answers.

Predicted value =
Residual =
