Multiple regression was used to model the relationship between several predictor variables and

system downtime. The coded equation obtained was:

 

Y = 16.4X1 + 2.55X2 - 4X3 + .2X4 - 5X2*X3 + 55

 

where Y is the system downtime (minutes/month) and X1, X2, X3, and X4 are the predictor

variables. For this model, all predictor variables had a P value less than .05 and the variance

inflation factors (VIF) were less than 1. The coefficient of determination (R-Sq) is .98.

 

Assume the cost and ease associated with influencing each variable by one unit is the same.

Decreasing which predictor variable by one unit while holding the others constant will most

significantly reduce system downtime?
