Transcribed Image Text:PULL STRENGTH
Which of the following is a correct equation of the linear model?
Predicted pull strength = 2.264 + 2.744wirelength + 0.013dieheight
%3D
Pull strength = 2.264 + 2.744wirelength + 0.013dieheight
Predicted pull strength = -2.264 + 2.744wirelength + 0.013dieheight
O 2.264 Pull Strength = 2.744wirelength + 0.013dieheight
Predicted pull strength = 2.744wirelength + 0.013dieheight
Pull strength = 2.744wirelength + 0.013dieheight
