+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.

How many degrees of freedom will be present for the “SST” term in the ANOVA table 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”)
