Transformed R 2 improved to 84.61%, but the categorical variable for cases above and below 30 o latitude could only be claimed with 84.7% confidence. Removing that variable showed similar significance for temperature and population predictors but reduced transformed R 2 to 65.27%. R 2 only improved to 30.92%, which is still an insignificant amount of variance explained. Normal probability plots of residuals also indicate a poor fit for the modelnormality was rejected with a p-value of 0.028.
