F-ratio test in middle of page 71, test whether
x1=x3
NOTE: SPSS does not allow direct testing for equal slopes, therefore we
have to use an incremental F-test using equation (3.48) and evaluate it using
the equation in the middle of page 71.
compute w = x1 + x3. exe. regression /dependent = y /method = enter w.
regression /dependent = y /method = enter x1 x3.
NOTE: F for x1=x3: [((.708-.669)/(2.1))/((1-.708)(30-2-1)) = 3.65.

compute yprime = y - x3. compute v = x1-x3. exe. regression /dependent = yprime /method enter = v.
NOTE: The regression coefficient for x3 is 1 – v = .306.
