Comment on how well the model fits the data:
One way to see if the model fits the data or not is to see the p-value of the ANOVA table. If the p-value is smaller than 5%, it fits the data well. Otherwise, it does not fits, meaning, the severance pay has little relations of all these independent variables.
What is the p-value of the model? Tip: If the answer is 1.2345E-5, means: 0.000012345. for 4 decimals, the answer is 0.0000 or 0.
Homework Answers
here pvalue is 0.000 aif we round to 4 decimals places.
here p value is small than 0.05 hence model is statistically significant .
and model fits the data well.

Forty refrigerators from two different models of a refrigerator manufacturer are compared to see if the smaller model uses less energy than the larger model. The energy was measured in kilowatt hours per month (kwh/mo). From years of testing these models, it is known that the standard deviation of kwh/mo is 34 kwh/mo for the smaller model and 40 kwh/mo for the larger one. From this survey, the sample means and standard deviations are 125 and 34, and 90 and...
