Question #1
Report Error
The circular test is satisfied if an index allows comparison of period 2 with period 0 via period 1, i.e., P₀₁ × P₁₂ = P₀₂. Which index commonly fails this test?
Correct Answer: Option C
Explanation:
Laspeyres index uses fixed base-period weights, so P₀₁ × P₁₂ ≠ P₀₂ in general due to weight rigidity, failing the circular test; Fisher's index satisfies it under certain conditions.

In a well-shuffled deck of 52 cards, the probability of drawing an ace is:
Correct Answer: Option B
