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: 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 selected at random. Data were collected for each, and their performances on the new machines were recorded. A few results are: Performance Length of Mechanical Prior on New Time in Aptitude On-the-Job Machine, Industry. Score, Performance Age, Name Y X1 X2 X3 X4 Mike 116 3 395 127 43 Miraglia Sue Trythall 112 9 378 130 28 The equation is: Ý = 10.9 + 0.5X1 + 0.186X2 +0.612X3 +0.008X4

(Click to select) dependent, (Click to select) independent (c) What is the number 0.612 called? (Click to select) (d)As age increases by one year, how much does estimated performance on the new machine increase? (Round your answer to 3 decimal places.) (e)Carl Knox applied for a job at Photo Works. He has been in the business for 11 years, and scored 375 on the mechanical aptitude test. Carl's prior on-the-job performance rating is 90, and he is 28 years old. Estimate Carl's performance on the new machine. (Round your answer to 3 decimal places.)
