Examine the accompanying sample data for the Variablies y and x. Compiete parts a through d below. 2 3 4 5 y 2 4 3 UA. I nere appears to De a positive iinear reiationsnip between x ana y, because y decreases as x increases. O B. There appears to be a negative linear relationship between x and y, because y decreasesas x increases. C. There appears to be a negative linear relationship between x and y, because y increasesas x increasos. D. There appears to be a positive linear relationship between x and y, because y increases as x increases. OE. There appears to be no relationship between x and y. b. Calculate the sum of squares error for the following equations: (1) y= -0.3+ 1.6x, (2) ý= -0.9 +0.6x, and (3) y= -0.1+1.1x. The sum of squares error for the equation y -0.3 + 1.6x is The sum of squares error for the equation y -0.9 +0.6x is The sum of squares error for the equation y = -0.1+1.1x is (Round to two decimal places as needed.)
