Refer to Exercise and the Modelling and Simulation in Materials Science and Engineering (Vol. 13, 2005) study in which engineers built a regression model for the tensile yield strength (y) of a new steel alloy. The engineers discovered that the independent variable nickel (x4) was highly correlated with the other 10 potential independent variables. Consequently, nickel was dropped from the model. Do you agree with this decision? Explain.
