In a simple linear regression setting, the deterministic model equation determines an exact value of the dependent variable y when the value of the independent variable x is given, since all points must lie exactly on the line.
  Indicate whether the statement is true or false

Q. 2

Q. 5

A complete 3 x 2 factorial experiment is called balanced if:
