Refer to the quarterly value of Gross Domestic Product (GDP in billions of currentdollars) in China from 2021q1 to 2023q4. You are going to analyze GDP by an additivemodel with a trend component (Tt) and a seasonal component (St), and forecast GDPusing the seasonal decomposition method.YearQuartertGDP (Y+)CM(4)Detrended202111249202228284.93329128.8??4432589.9??20221527034.4??2629244.7??3730794.2??4833399.1??20231928442.3??21030829.3??31131997.641234789a. Use an CM(t|4) [centered moving average of order 4] series to estimate the GDPseries from t=3 to 10.b. Calculate the seasonal factors for each quarter with a zero mean, by first obtainingthe detrended revenue series from t = 3 to 10.c. In this seasonal decomposition method, why is it necessary to use moving averagesto process time series data first? How about using moving average of order 5?

Suppose the relationship between the government's tax revenue (T) and national income (Y) is represented by the equation T = 30 +0.5Y. Plot this relationship on a scale diagram, with Y on the horizontal axis and T on the vertical axis. Interpret the equation. Use the line drawing tool to draw the equation. Make sure to plot the vertical axis as one endpoint of the line. Properly label this line. Carefully follow the instructions above, and only draw the required objects.
This case study focuses on the Australian economy in 2019, before the COVID-19 pandemic hit. On 4th September 2019, the Australian Bureau of Statistics (ABS) published Real GDP data for the quarter ending June 2019. (The reporting of GDP always lags by about 2 months as it takes time to collect and compile data). The data showed that the Australian economy recorded quarterly growth of 0.5%. However, there was a decrease in Real GDP per capita. Furthermore, Real GDP per capita in June 2019 was lower than it was a year before (June 2018). Overall, while Real GDP still increased, the growth was very weak; the weakest on record since March 2001. (Source: Australian Financial Review and The Guardian). Required: Question 1. Clearly explain what Real GDP per capita means.Clearly explain why Real GDP per capita decreased whereas there was still growth in Real GDP for the quarter ending June 2019. Question 2. Given the economic conditions described above, predict how the following key…
