Extracted text: Which of the following is TRUE? In a good regression model, the residuals plot shows a random pattern. Sum of squares regression (SSR) can be equal to total sum of squares I. I. (SST). Changing the units of measurement for x or y changes the correlation I. coefficient. I and Il only I and III only O 1, Il and IlI O Il and III only If the sum of squares regression (SSR) is 150, which of the following must be TRUE? The proportion of unexplained variation is less than 150. The sum of squares error (SSE) must be greater than 150. The total sum of squares (SST) is at least 150. The coefficient of correlation is 0.9.
