Question 1 A multiple regression analysis produced the following tables. Predictor Coefficients Standard Error t Statistic p-value 154.5534 3.990108 0.000947 1.43058 0.170675 1.780075 0.33560S 5.30407 5.83E-05 Intercept 616.6849 3.33833 X1 2.333548 Sourcedf MS p-value Regression 2 121783 60891.48 14.76117 0.000286 Residual 15 61876.68 4125.112 Total 17 183659.6 These results indicate that x2 is significant at the 5% level none of the predictor variables are significant at the 5% level X1 is significant at the 5% level the intercept is not significant at 5% level each predictor variable is significant at the 5% level

Explanation / Answer

1. x2 is significant at the 5% level as p-value is less than 0.05.

2. Only x1 is not significant at the 5% level as p-value is greater than 0.05.

3. Same as 2.

4. The intercept is significant at 5% level as p-value is less than 0.05.

5. Same as 2.

Hence, only option 1 is correct.
