14. 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 (5% significance level to make a clear conclusion about the effectiveness of the model.
The regression equation is Y =81,2- 0.0119X
Predicator Coef SE coef T P
Constant 81.18 11.65 6.97 0.000
X -0.01191 0.00993 -1.20 0.245
Sample slope:
p-value:
does the X appear to be an effective predicator of the response variableY?
