In: Statistics and Probability
We have a dataset with n = 10 pairs of observations (xi; yi), and Xn i=1 xi = 683; Xn i=1 yi = 813; Xn i=1 x2i = 47; 405; Xn i=1 xiyi = 56; 089; Xn i=1 y2 i = 66; 731: What is the line of best t for this data?
Here we are given with details
n = 10





we know that best fit line is given by :

where



and

So from above equations

and

So the best fitted line is
