Six years of quarterly data of a seasonally adjusted series are used to estimate a lineartrend model as T t=181.60 + 1.44t. In addition, quarterly seasonal indices arecalculated as § 1= 0.85, § 2= 0.91, Ŝ 3 = 116, and § 4= 119.a-1. Interpret the first quarterly index. In other words, what is the value of the series inthe first quarter as compared to the average?15% aboveO 85% belowO 15% below85% abovea-2. Interpret the fourth quarterly index.
