If a set of data contains no values of x that are equal to zero, then the regression coefficient, b0, has no particular meaning.
 
  Indicate whether the statement is true or false

Question 2

Based on the correlations below:
 
  Y
  X1 0.8
  X2 0.7
 
  we could say that x1 accounts for 64 percent of the variation in y and x2 accounts for 49 percent of the variation in y. So if both xs are included in a multiple regression model, then the resulting R-square = 1.13.
   Indicate whether the statement is true or false
