*PLEASE CHOOSE 1 CORRECT OPTION*

Explanation / Answer

A.

Given linear trend equation    Y^(t) = 4.53 + 1.54t

Beginning in 2005 ,The estimated value for 2008 , so t= 4

Y^(4 )= 4.53 +1.54(4) = 10.69 ( in millions of dollars)

Option is B

B.

Option B. records future performance

C

Given linear trend equation    Y^(t) = 500 + 60t

Sales starting from 2005 to 2009, estimated sales for 2010 is, so t= 6

Y^(6) = 500 + 60(6) =$860 ( in thousands )

Option is B
