Question
Computer output for fitting a simple linear model is given below. State the value of the sample slope for this model and give the null and alternative hypotheses for testing if the slope in the population is different from zero. Identify the p-value and use it (and a 5% significance level) to make a clear conclusion about the effectiveness of the model.
The regression equation is Y=84.1-0.015X.
| Predictor | Coef | SE Coef | T | P |
|---|---|---|---|---|
| Constant | 84.08 | 12.06 | 6.97 | 0.000 |
| X | -0.01501 | 0.01251 | -1.20 | 0.245 |
Sample slope: Enter your answer; sample slope
p-value: Enter your answer; p-value
Does X appear to be an effective predictor of the response variable Y?
Choose the answer from the menu; Is the model effective?
