(Situation L) a Farmer's Marketing Cooperative Recorded the Volume of Wheat

(Situation L) A farmer's marketing cooperative recorded the volume of wheat harvested by its members from 1991-2004.
The cooperative is interested in detecting the long-term trend of the amount of wheat harvested. The data collected is shown in the table.
$$\begin{array} { l c c } \hline \text { Year } & \text { Time } & \begin{array} { c } \text { Wheat Harvested by Coop. Member } \\\text { (y, in thousands of bushels) }\end{array} \\\hline 1991 & 1 & 75 \\1992 & 2 & 78 \\1993 & 3 & 82 \\1994 & 4 & 82 \\1995 & 5 & 84 \\1996 & 6 & 85 \\1997 & 7 & 87 \\1998 & 8 & 91 \\1999 & 9 & 92 \\2000 & 10 & 92 \\2001 & 11 & 93 \\2002 & 12 & 96 \\2003 & 13 & 101 \\2004 & 14 & 102 \\\hline\end{array}$$
-Suppose the least squares regression equation is $\hat { y } _ { t } = 75 + 2 t$ Interpret the estimate of $\beta _ { 1 }$ in terms of the problem.

A) We expect the mean volume of wheat harvested to increase 2000 bushels from one year to the next.
B) We expect the volume of wheat harvested to increase 2000 bushels for each additional corporate member.
C) We expect the volume of wheat harvested to be 2000 bushels in any given year.
D) We expect to harvest 2000 bushels of wheat in 2005.
