Complete parts a through d below. Describe the relationship between x and y. choose the correct answer below A. There appears to be a negative linear relationship between x and y, because yincreasesasxincreases. o There appears to be a positive linear relationship between x and y, because y decreases as x increases. B. O c. There appears to be a negative linear relationship between x and y, because y decreasesas x increases o D. There appears to be a positive linear relationship between x and y, because y increases as xincreases O E. There appears to be no relationship betweenxand y b. Calculate the sum of squares error for the following equations: (1) +3.8 +0.2x, (2) y 3.2 0.2x, and (3) y 2.9 1.3x. The sum of squares error for the equation y 3.8 +0.2x is The sum of squares error for the equation y 3.2 +0.2x is The sum of squares error for the equation y-2.9 1.3x is 3 Round to two decimal places as needed) c. Which of these equations provides the best fit of these data? Describe the criterion used to determine best fit A The equation y 3.2 0.2x provides the best because it has the lowest sum of squares error This criterion is calle Click to select your answer(s) O Search right here
