Question

D Question 1 Select the best description for the symbols βί and β0 in a lnear model ßi is the population intercept and β0 is the population slope respectively βί is the sample intercept and β0 is the sample slope respectively. B is the population slope and Bo is the population intercept respectively β1 is the sample slope and β0 is the sample intercept respectively. o ๏ DQuestion 2 Select the best representation of the population regression line.

Answer 1

Answer

(1) We know that regression equation is given as

where bo is sample intercept and b1 is sample slope

and population regression equation is given as

where $eta_o$ is population intercept and is population slope.

So, option C is correct.

(2) It is already mentioned in the above question that the population regression equation is whereas sample regression equation is given as

So, option D is correct answer for population regression equation.
