Course: Statistics - Lineal Regression

Property brokers often need to know how appraisal of a property changes (in thousands of $) in relation to its surface area (hundreds of square meters). Table below is a sample of 10 properties in city of Santiago, Chile.

X	1.1	1.6	1.5	1.6	1.4	1.3	1.1	1.7	1.9	1.5
Y	4.0	4.9	5.4	5.1	4.8	4.6	4.1	5.6	6.2	5.0

a) Using the least squares method, determine linear regression line. Graph it.
b) Is it possible to state that relationship between appraisal and its area is significant? Use α = 5%.
