3) A coworker is considering the use of a log linear (power) model using weight to estimate the cost of a missile engine. 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 = 1.109438 Log Space b0 = -0.122932
Cost = 0.884324 (Weight) 1.109438
Cost = 0.884324 + 1.109438 (Weight)
Cost = 2.421347 (Weight) 1.109438
Cost = 1.109438 + 0.884324 (Weight)

| Cost = 0.884324 (Weight) 1.109438 |
| Cost = 0.884324 + 1.109438 (Weight) |
| Cost = 2.421347 (Weight) 1.109438 |
| Cost = 1.109438 + 0.884324 (Weight) |
Solution
b1 = slope = 1.109438
b0 = intercept = -0.122932
Hence regression equation will be
y = 1.109438 x+anti log of (-0.122932) where x is weight and y is cost
Proper choice will be hence
Cost = 1.109438 (weight)+0.884124
