regression model is 46

You have been given a dataset, which consists of project delay and cost data for 500 projects. You are asked to develop a regression model for these two measures, considering the cost as the dependent variable and the delay as the independent variable. Based on this dataset, you then found that the sum of squared errors for the mean-based model is 60 . For the regression model, it is (40+ the last digit of your SID). Find out the R-squared value for your regression model
