Butler Trucking Company has developed a regression equation to predict the delivery time for its drivers (y). The model is based on the miles traveled (x 1), the number of deliveries (x 2) and whether or not the travel will occur during rush hours (x 3 - 1 if during rush hour and 0 if not during rush hour). The regression equation that they use is y

The answer is Y = 6.3973.

Step-by-step explanation:

Solution

Given that:

The regression  equation is given below:

Y = - 0.3302 + 0.0672 x₁ + 0.6735 x₂ + 0.9980 x₃

Now,

When x₂ = 5, x₁ = 50, x₃ = 0

Y = - 0.3302 + 0.0672 * 50 +0.6735 * 5

Y=  - 0.3302 + 3.36 + 3.3675

Y = 6.3973

Therefore the time (hour) it will take for the driver to make five deliveries on a 50 mile journey not during rush hour is 6.3973.
