Question 1

+1 markNumerical 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 adjusted R-square value for the model?
(Note: Enter the answer as a numeric percentage value rounded to two decimal places without the % symbol. For example, if your answer is “10.256 %”, enter it as “10.26”)
