Consider the following data:

X	Y
1	13
3	10
5	9
5	5
6	3

Draw a Scatter Plot of the data.

Do you believe the correlation coefficient r will be positive, negative or close to zero? Why

What is your estimate to the value of Y associated with X=4?

Expert Solution

Solution:

• Scatter diagram is:

Using the above scatter diagram, i believe that correlation coefficient between x and y will be negative.

• Regression equation is:

For X= 4 estimate value of Y?

Y=15.25 - 1.8125 X

Y=15.25 - 1.8125*4

Y=8
