Consider the following statements: I.   Multicollinearity is present when there is a high degree of linear correlation between the residuals. II.  A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: y-hat = 135 + 6x + errors.  This implies that if the height is increased by 1 inch, the weight increases by 6 pounds in this linear model.   a. I is true and II is false.   b. I is false and II is true.   c. Both I and II are true.   d. Both I and II are false.   e. More information is needed for each statement in order to tell which is true or false.

Question

  1. Consider the following statements:

    I.   Multicollinearity is present when there is a high degree of linear correlation between the residuals.

    II.  A regression analysis between weight (y in pounds) and height (x in inches) resulted in the following least squares line: y-hat = 135 + 6x + errors.  This implies that if the height is increased by 1 inch, the weight increases by 6 pounds in this linear model.

      a.

    I is true and II is false.
      b.

    I is false and II is true.
      c.

    Both I and II are true.
      d.

    Both I and II are false.
      e.

    More information is needed for each statement in order to tell which is true or false.
