Giving reasons, state whether the following statements are true or false

Giving reasons, state whether the following statements are true or false.
(i) Average Propensity to Save is always greater than zero.
(ii) Value of investment multiplier varies between zero and infinity.

(i) No, the statement is false. When consumption is greater than the income level, the value of Average Propensity to Save is less than zero or negative.
(ii) No, the statement is false. We know that,
K = 1 / 1-MPC , so, even if the MPC will have its minimum value, i.e. zero, the investment multiplier will be 1.
Similarly, when MPC = 1, the value of investment multiplier is infinity. So, we can say that the value of investment multiplier varies between 1 and infinity.
