Find the equation of the regression line of y on x, if the observations (x, y) are as follows : (1,4),(2,8),(3,2),(4,12),(5,10),(6,14),(7,16),(8,6),(9,18)Also, find the estimated value of y when x = 14.
Given that the observations are: (9, -4), (10, -3), (11, -1), (12, 0), (13, 1), (14, 3), (15, 5), (16, 8). Find the two lines of regression and estimate the value of y when x = 13·5.
