Question #930
Which of the following index numbers uses the weighted arithmetic mean of price relatives with base year value weights?
A. Fisher index
B. Paasche index
C. Laspeyres index
D. The Laspeyres index can be expressed as weighted arithmetic mean of price relatives with base period values as weights.
