Given are five observations for two variables, x and y. * 1 1 2 3 4 5 Y1 3 8 5 10 14 (a) Develop a scatter diagram for these data. 187 18 7 18 15 15 15 12 12 12 12 9 6 3 5 2 3 5 1 2 3 5 (b) What does the scatter diagram developed In part (a) Indicate about the relationship between the two variables? There appears to be a negative linear relationship between x and y There appears to be a positive linear relationship between x and y There appears to be no noticeable relationship between x and y. (c) Try to approximate the relationship between x and y by drawing a straight line through the data. 18 18 18 15 18 15 15 12 12 12 12 3- 3 DO (d) Develop the estimated regression equation by computing the values of bo and b, using bj = E( x, - x ) (y, - >) (x / - x)2 2 and bo = y - b , x . (e) Use the estimated regression equation to predict the value of y when x = 4. Submit
