Financial Risk Manager Part 1

The question appears to be incomplete as it cuts off after stating "the sum of squared residuals is" without providing the actual value or the multiple choice options. Without the complete question and options, I cannot determine the correct answer or provide a proper explanation. This appears to be a regression analysis question that would typically involve calculating R-squared, adjusted R-squared, F-statistic, or other regression statistics given the total sum of squares (SST = 540) and sum of squared residuals (SSR). To properly answer this question, the complete text with all options is needed.
