Question 1:

Given are five observations for two variables, x and y. 1 2 3 4 (a) Develop a scatter diagram for these data.

Question 2:

Answer 1

1)

a) The scatter plot is given as.....

b) The diagram in part a) indicates that..

0 1 2 3 4 5 6

There appears to be a +ve linear relationship between X and Y

C)

1 2 3 4 5 6

Question 2)
