Given are five observations for two variables,xandy.

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 betweenxandyby drawing a straight line through the data.

d. Develop the estimated regression equation by computing the values ofb0 andb1 using equations (12.6) and (12.7).

e. Use the estimated regression equation to predict the value ofywhenx= 10.
