A Sample of 33 Companies Was Randomly Selected and Data $\text{Response Variable is Turnover Rate}$

A sample of 33 companies was randomly selected and data collected on the average annual Bonus, turnover rate (%) , and trust index (measured on a scale of 0 - 100) .In a multiple Regression estimating turnover rate using average bonus and trust index, what is the correct Null hypotheses for testing the regression coefficient of Trust Index?

$\text{Response Variable is Turnover Rate}$

$\begin{array} { l r r r r } \text { Predictor } & \text { Coef } & \text { SE Coef } & \text { T } & \text { P } \\ \text { Constant } & 12.1005 & 0.7826 & 15.46 & 0.000 \\ \text { Trust Index } & - 0.07149 & 0.01966 & - 3.64 & 0.001 \\ \text { Average Bonus } & - 0.0007216 & 0.0001481 & - 4.87 & 0.000 \end{array}$

A) $\beta { } _ { \mathrm { TI } } \neq 0$
B) $\mathrm { T } _\mathrm { TI } > 0$
C) $\beta { } _ { \mathrm { TI } } = 0$
D) $\beta { } _ { \mathrm { TI } } < 0$
E) $\mathrm { T } _ { \mathrm { TI } } \leq 0$
