# Regression

Given are five observations for two variables x and y. (see attached for details)

x y

1 3

2 7

3 5

4 11

5 14

A. Develop a scatter diagram for this data.

B. What does the scatter diagram in part A indicate about the relationship between the two variables?

C. Try to aproximate 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 b (0) and b (1) using equations(14.6) and (14.7)

E. Use the estimated regression to predict the value of y when x = 4
