Thompson Photo Works purchased several new, highly sophisticated processing machines. The production department needed some guldance 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: x = Length of time an employee was in the Industry x2 = Mechanical aptitude test score X3 = Prior on-the-job rating 4 - 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. Name Mike Miraglia Sue Trythall Performance on New Machine, y 118 118 The equation is: = 11.6+0.5x + 0.186x2 +0.212x + 0.002x4 a. What is this equation called? Multiple regression equation Multiple standard error of estimate Coefficient of determination Length of Time in Industry, x1 5 7 b. How many dependent and Independent variables are there? dependent, independent. c. What is the number 0.186 called? Regression coefficient Coefficient of determination Homoscedasticity Multicollinearity Mechanical Aptitude Score, x2 349 345 Prior On-the-Job Performance, Age, x3 x4 123 34 115 21 d. As age Increases by one year, how much does estimated performance on the new machine Increase? (Round your answer to 3 decimal places.) The estimated performane increases by e. Carl Knox applied for a job at Photo Works. He has been in the business for 10 years and scored 260 on the mechanical aptitude test. Carl's prior on-the-job performance rating is 90, and he is 45 years old. Estimate Carl's performance on the new machine. (Round your answer to 3 decimal places.) Estimated performane
