Thompson Photo Works purchased several new, highly sophisticated processing machines. The production department needed some
guidance with respect to qualifications needed by an operator. Is age a factor? Is the length of service as an operator (In years)
Important? To evaluate the factors needed to estimate performance on the new processing machines, four variables were selected:
X₁ = Length of time an employee was in the Industry
x₂ = Mechanical aptitude test score
x3 = Prior on-the-job rating
X4 = Age
Performance on the new machine is designated y.
Thirty employees were randomly selected and data were collected for each of the variables. A few results follow:
