Question: We estimated a model using G.P. A. to predict the starting salaries of new college graduates and obtained the following information with alpha = 0.05.
We estimated a model using G.P. A. to predict the starting salaries of new college graduates and obtained the following information with alpha = 0.05. What can be said about the probability of the overall model?
| Sum of Squares | Degrees of Freedom | Mean Square | F-Statistic | Probability of F | |
| SSR | 684.4652 | 1 | 684.4652 | 62.5756 | 2.4214E-05 |
| SSE | 98.4439 | 9 | 10.9382 | ||
| SST | 782.9091 | 10 |
Group of answer choices
The F-statistic is too low, so G. P. A, can not be used to predict starting salaries.
The probability of F is larger than alpha, so we reject the model.
This model is not a good predictor for starting salaries.
We can not answer the queston based on the information provided.
The probability level of the F statistic indicates that the model is useful.
