1. Multicollinearity is a situation in which two or more independent variables are highly correlated with each other. 2. In a multiple regression problem, the regression equation is y^=60.6−5.2x1+0.75x2. The estimated value for y when x1=3 and x2=4 is 48. 3. In a multiple regression problem involving 24 observations and three independent variables, the estimated regression equation is y^=72+3.2x1+1.5x2−x3. For this model, SST=800 and SSE=245. The value of the FF statistic for testing the significance of this model is 15.102.
Select True or False for each statement, depending on whether the corresponding statement is true or false.
