An Analysis Results in a Multiple Regression Equation Of $y ^ { \prime } = 93 + 23 x _ { 1 } + 4 x _ { 2 }$

An analysis results in a multiple regression equation of $y ^ { \prime } = 93 + 23 x _ { 1 } + 4 x _ { 2 }$ We can conclude that

A) The variable $\mathrm { X } _ { 1 }$ is a very significant factor in this model
B) The variable $\mathrm { X } _ { 1 }$ is a moderately significant factor in this model
C) The variable $\mathrm { X } _ { 1 }$ is not a significant factor in this model
D) This is insufficient information to assess the significance of $\mathrm { X } _ { 1 }$
