Given are five observations for two variables, x and y.

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 equations (14.6) and (14.7).
e. Use the estimated regression equation to predict the value of y when x = 4.
