An aircraft company wanted to predict the number of worker-hours necessary to finish the design of a
Question:
y` = β0 + β1x1i + β2x2i + β3x3i + εi
where
yi = design effort, in millions of worker-hours
x1i = plane’s top speed, in miles per hour
x2i = plane’s weight, in tons
x3i = percentage number of parts in common with other models
The estimated regression coefficients were as follows:
b0 = 2 b1 = 0.661 b2 = 0.065 b3 = -0.018
Interpret these estimates.
