Interpret the results of the following

Solution-

Estimated regression equation is-

Y = 4.90e-08 -5296.638 * X1 + 31300.68 * X2

value of cofficient of determination = 0.26

This means that percentage of total variation in the dependent variable explained by the model.

To, check the overall significance of the model, we will consider the p-value from the anova table-

p-value= 0.000

This is less than 0.05 hence null hypothesis-model is insignificant is rejected

and thus model exists.
