Given are five observations for two variables, x and y. (a) Develop a scatter diagram for these data. (i) (i) (b) What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? There appears to be a positive linear relationship between x and y. There appears to be no noticeable relationship between x and y. There appears to be a negative linear relationship between x and y. (c) Try to approximate the relationship between x and y by drawing a straight line through the data. i) (d) Develop the estimated regression equation by computing the values of b0 and b1 using b1=(xix)2(xjx)(yjy) and b0=yb1x. y^=.
