Question 2

+0.5 marksNumerical answer

A regression model is fit on a dataset with 500 data points. The total variability (magnitude) in the dependent variable is 1,12,43,679. The final model is as specified below. The model was able to explain 87% of the variability in the dependent variable.

Given this information answer the given subquestions.

What is the total variability (magnitude) that is present in the error terms for this model? (Note: Enter the answer rounded to two decimal places. For example, if the answer is “1.234”, then enter it as “1.23”)
