Six years of quarterly data of a seasonally adjusted series are used to estimate a linear trend model as T1 = 194.40 + 1.23t. In addition, quarterly seasonal indices are calculated as S, = 0.94, S2 = 0.88, S3 = 1.20, and S4 = 1.02. a-1. Interpret the first quarterly index. In other words, what is the value of the series in the first quarter as compared to the average? 94% below O 6% above 94% above 6% below a-2....
Six years of quarterly data of a seasonally adjusted series are used to estimate a linear trend model as TˆT^ t = 183.40 + 1.07t. In addition, quarterly seasonal indices are calculated as SˆS^ 1 = 0.80, SˆS^ 2 = 0.98, SˆS^ 3 = 1.02, and SˆS^ 4 = 1.04. a-1. Interpret the first quarterly index.

Question 3 (0.75 points) The following linear trend equation is used to predict quarterly demand: Y1 = 300 - 2t, where t= 1 in the first quarter of year 2020. Quarterly seasonal indices for each quarter are given as Si = 0.7; S2 = 1.6; S3 = 0.5 and S4 = 1.2, respectively. Calculate the seasonally adjusted forecast for the second quarter of 2021?
