  1. True
  2. False

Question 23

Which statement(s) are true about the Fitted Line Plot shown here? (Note: There are 2 correct answers).

  1. When Reactant increases, the Energy Consumed increases.
  2. The slope of the equation is a positive 130.5.
  3. The predicted output Y is close to -18 when the Reactant level is set to 6.
  4. Over 85 % of the variation of the Energy Consumed is explained by the Reactant via this Linear Regression.

Question 24

After reviewing the Capability Analysis shown here select the statement(s) that are untrue.
