Coefficients
Term Coef SE Coef T-Value P-Value VIF
Constant 1118.5 39.5 28.34 0.000
%Takers -2.547 0.187 -13.62 0.000 1.05
T/S Ratio -3.73 2.21 -1.69 0.098 1.05
Assuming those conditions are satisfied, which of the following gives a correct interpretation of the p-value of T/S Ratio?
A) At the 10% significance level, T/S Ratio is a significant linear predictor.
B) At the 10% significance level, T/S is a significant linear predictor in combination with %Takers.
C) At the 5% significance level, T/S Ratio is not a significant linear predictor in combination with %Takers.
D) Both b and c.
Please explain how you arrived to each of the answers. Thanks!
Explanation / Answer
Assuming those conditions are satisfied, which of the following gives a correct interpretation of the p-value of T/S Ratio?
B) At the 10% significance level, T/S is a significant linear predictor in combination with %Takers.
C) At the 5% significance level, T/S Ratio is not a significant linear predictor in combination with %Takers.
well since p value is lower tahn 0.10 we conclude that , but since p value is greater than 0.05 we conclude thtat thereis no significant linear predictor
