Given are five obersvations for two variables, x and y.
xi - 1 2 3 4 5
yi - 3 7 5 11 14
a. Develop a scatter diagram for these data.
b. What does the scatter diagra 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 value of bo and bi using equations.
e. Use the estimated regression eqution to predict the value of y when x = 4.
