An analysis results in a multiple regression equation of $y ^ { \prime } = 68 + 27 x _ { 1 } + 2 x _ { 2 }$. We can conclude that
A) The variable $x _ { 1 }$ is not a significant factor in this model.
B) This is insufficient information to assess the significance of $x _ { 1 }$.
C) The variable $x _ { 1 }$ is a moderately significant factor in this model.
D) The variable $x _ { 1 }$ is a very significant factor in this model.

The coefficients in a regression equation (27 for $x_1$ and 2 for $x_2$) do not directly indicate the significance of the variables. Significance is determined by statistical tests (e.g., t-tests) and p-values, which are not provided here.
