Please answer all parts accurately Given are five observations for two variables, x and y (a) Develop a scatter diagram for these data. (c) Try to approximate the relationship between x and y by drawing a straight line through the data. (i) ii (d) Develop the estimated regression equation by computing the values of b0 and b1 using b1=(xix)2(xix)(yiy) and b0=yb1x. y^= (e) Use the estimated regression equation to predict the value of y when x=13..
