Question

10.00 points Thompson Photo Works several new, highly sophisticated processing machines The producton department needed some guidance with respect to qualifications needed by an operator. Is age a fador ls the length of service as an operator (in years) important? In order to explore further the factors needed to estimate on the new processing machinos, our variablos 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 new Thirty employees were selected at random Data were collected for each, and their performances on the machines were recorded. few are Performance Length of Mechanical Prior on New Time in Aptitude On the lob Machine, Industry Score, Performance, Age, X1 Mike Miraglia 112 12 312 52 Sue Trythall 113 380 123 27 The equation is Y 116, 0.4x, 0.286x2 0, 112x, .0002x

Explanation / Answer

Solution:-

d) If age (X4) increase by 1 unit then the performance on new machine is increase by 0.002

Regression equation is:-

Yhat = 11.6 + 0.4 *X1 + 0.286*X2 + 0.112*X3 + 0.002*X4

If age (X4) increase by 1 unit then the performance on new machine is increase by 0.002

e) Estimated carl's performance on new machine is Yhat = 26.650

Yhat = 11.6 + 0.4 *X1 + 0.286*X2 + 0.112*X3 + 0.002*X4

X1 = 6

X2 = 280

X3 = 97

X4 = 35

Yhat = 11.6 + 0.4 × 6 + 0.286 × 280 + 0.112 × 97 + 0.002 × 35

Yhat = 26.65
