(Solved) A coworker is considering the use of a log linear (power) model using weight to estimate the cost of a utility vehicle

  1. A coworker is considering the use of a log linear (power) model using weight to estimate the cost of a utility vehicle. They have performed the following calculations in log space using natural logarithms. Select the corresponding unit space form of this power model equation.

    Log Space b1 = 1.268074 b0 = 0.062153
    Cost = 0.062153 + 1.268074 (Weight)
    Cost = 1.268074 + 0.062153 (Weight)
    Cost = 1.064125 (Weight) 1.268074
    Cost = 0.062153 (Weight) 1.268074

  2. You are estimating the fuel consumption (gallons per mile) for intermediate armored vehicles based on the horsepower of the vehicle. The vehicle for which you are estimating has 4.5 hundred horsepower. Given the following equation, select the correct response from each pair.
    Fuel Consumption = – 0.03 + 0.22 (Horsepower in hundreds)
    The dependent variable is Horsepower
    The dependent variable is Fuel Consumption
    The y-intercept is 0.22
    The y-intercept is – 0.03
    The estimated fuel consumption for your vehicle is .96 gallons per mile
    The estimated fuel consumption for your vehicle is 1.02 gallons per mile
