3.A linear trend line was fitted to a deseasonalised set of quarterly data for 2020. From the equation of the trend, we see thatthe values of the intercept and slope are 256 and 15.6, respectively. The normalised seasonal indices for the first three quarters are 1.2, 0.7 and 0.8, respectively.Based on this information, the seasonally adjusted forecast value for the fourth quarter of 2020 is _____. Note: Y is deseasonalised data and X is quarter number (coded 1, 2, 3 and 4).

a.413.92

b.382.08

c.244.92

d.222.80
