(a) The total variation in the sample y-values is given by the (Choose one) (Choose one) ▼ error sum of squares total sum of squares regression sum of squares which for these data is (b) The value is the proportion of the total variation in the sample y-values that is explained by the estimated linear relationship between x and y. For these data, the value of ² is. (Round your answer to at least 2 decimal places.) (c) The least-squares regression line given above is said to be a line that "best fits" the sample data. The term "best which for these fits" is used because the line has an equation that minimizes the (Choose one) data is (Choose one) ▼ L
