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? In order to explore further the factors needed to
estimate performance on the new processing machines, four variables
were listed:
Thirty employees were selected at random. Data were collected
for each, and their performances on the new machines were recorded.
A few results are:
As age increases by one year, how much does estimated
performance on the new machine increase? (Round your
answer to 3 decimal places.)
Carl Knox applied for a job at Photo Works. He has been in the
business for 7 years, and scored 335 on the mechanical aptitude
test. Carl’s prior on-the-job performance rating is 65, and he is
41 years old. Estimate Carl’s performance on the new
machine. (Round your answer to 3 decimal
places.)
