Given are five observations for two variables, x and y. xi yi A. Develop a scatter diagram for these data. B. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? c. Try to approximate the relationship between x and y by drawing a straight line through the data. \. D. Develop the estimated regression equation by computing the values of b0 and b1 using b1 = (xi x)(yi y) (xi x)2 and b0 = y b1x. = E. Use the estimated regression equation to predict the value of y when x = 4. xi12345 yi4751113.
