Consider the following data:

X	2	4	1	5	0	8	8.5	2	4.5	10
Y	3	4	2.5	6	1	6	7	2	5.5	10

Use linear regression and calculate the regression coefficients and obtain the line of regression for this data. Show your steps.

Draw the data points and the line you estimated using linear regression.

Compute the Least Squares Line Fit ERROR for the line you find.

Do you think that we can find another regression method to get better regression results and less error? Justify you answer.

NOT: without coding.
