The relationship between X and Y is represented as a quadratic relationship and the summary regression output is shown below :
Coeff StdError t Stat p-value
Intercept 286.42 9.66 29.64 0.0001
X -0.31 0.06 -5.14 0.0006
X Sq 0.000067 0.00007 ******* 0.3647
What is the T-Stat value for the quadratic variable ?
