Hello students, today we will discuss about this question.
00:04
In this question, we are given that what does the equation y bar, y cap is equals to beta 0 cap plus beta 1 cap multiplied by x that denote if the regression equation, the regression equation, that is y is equals to beta 0 plus beta 1 x1 plus u.
00:33
Then here we need to find what does it denote that is equals to question one.
00:39
So here first of all, we can say that we have four options.
00:44
Option a, that is, it denotes the sample regression function.
00:54
Option b, that is the explained sum of squares.
01:05
Option c, that is the total sum of square, and option d, that is the population regression function.
01:27
So here, we can say that here we can write y that is equals to beta 0 plus beta 1x plus mu, that will be a population regression function...
