In reference to the above data, which of the following statements are correct? (where x=t−2013)
(A) If the equation of the straight line trend is y=12+2.29x, then the trend value for the year 2017 is 21.16.
(B) If the equation of the straight line trend is y=12+2.29x, then the trend value for the year 2013 is 11.
(C) If the equation of the straight line trend is y=12+2.29x, then the trend value for the year 2015 is 17.
(D) If (t1,y2),(t2,y2),(t3,y3),......,(tn,yn) denote the time series and yt are the trend values of the variable y, then ∑(y−yt)=0.
