4. When should I avoid the sign test and choose another method?
Avoid the sign test when sample size is extremely small, data are interval-scaled and roughly normal, or you need more power. Prefer the paired t-test, Wilcoxon signed-rank test, or permutation tests; these use magnitude information and often detect effects that the sign test cannot.

➤ Why does marginal utility typically decline as consumption increases?
Marginal utility falls because each extra unit usually provides less additional satisfaction than the previous one. The law of diminishing marginal utility explains this: basic wants get satisfied first, so subsequent units matter less. Satiation, storage limits, and shifting preferences cause the decrease in marginal benefit.

➤ How can I fill missing labor or capital entries when some table cells are blank?
Fill gaps by using TP differences across rows that keep the other input constant. If a row lists multiple labor values (for example “9, 12”), you must obtain TP for each labor level separately. When data are insufficient, request the missing TP or clearly state assumptions before interpolating values.

➤ How can I tell the difference between a movement along the demand curve and a shift in demand?
Check whether the whole relationship relocates or only a point moves. Movement along the curve means quantity demanded changed because of a price change. If the entire curve shifts right or left, demand changed due to factors like income, tastes, population, or price changes in substitutes and complements.
