Which of the following is not a true statement about the scientific method?

Based on the table introduced in question #12, what is the value for MPP that should appear in cell **C**?

A production possibility curve shows all combinations of two outputs which can be produced from a fixed amount of input.

A farm manager is trying to estimate the fixed costs associated with their crop production. The farm manager owns 500 acres of farmland that were purchased for $750 per acre in 1980, are currently worth $2,000 per acre (based on a market-basis balance sheet), and could be cash rented for $150 per acre. The current per-acre opportunity cost of the farmland is therefore best estimated as:

A positive economic profit must exist if a business shows a profit on its tax return.

At the level of input and output where marginal revenue is equal to marginal cost, total profit will always be positive.

Based on the table above, what is the marginal cost that should appear in cell **B**?

According to the equal marginal principle, a limited input should be allocated among competing uses in such a way that the marginal value products of the last unit used on each alternative are equal.
