Problem 2.3.115

Truck Rentals A truck rental company rents a moving truck for one day by charging $29 plus $0.20 per mile. Write a linear equation that relates the cost C, in dollars, of renting the truck to the number x of miles driven. What is the cost of renting the truck if the truck is driven 110 miles? 230 miles?

Step-by-Step Solution:
Step 1 of 3

Linear Regression Mathematical Models  Expression that describes the relationship between variables  2 types o Deterministic model o Probabilistic model  Hypothesize 2 components  Deterministic  Random error Straight line probabilistic model y =  0+  x1+ y  dependent variable x  independent variable E(y) = 0 + 1x  Deterministic component  (epsilon)  Random error component  0(beta zero) = y­intercept of the line  1(beta one) = slope of the line How do you determine what line “fits best” on a Scattergram Least Squares line  Sum of the errors = 0 o Mean error = 0
