9. The table below shows some time series data where t represents time. 1 14 17 18 2 4 24 21 19 7 16 8 13 (a) By using two point linear estimation, find the equation of the regression line in the form of x = a + bt. On a graph paper, use 2 cm to represent 1 unit on horizontal axis, plot a scatter diagram of the original data and the regression line. (b) (c) Create a 3-point moving average smoothing of the data. Hence, plot the smoothed data in your graph in (b). (d) Predict the temperature for t = 9 using (i) the last smoothed value; (ii) linear estimation.
