What is the difference between the following two regression equations? Choose the correct answer below. A. The first equation is for sample data; the second equation is for a population.
B. The first equation is for a population; the second equation is for sample data.

The correct option is (A). The first equation is for sample data; the second equation is for a population.

Step-by-step explanation:

According to the scenario, the following would be represented as a sample and the population

Y with caret = b0 + b1x = sample

and

y = b0 + b1x =  population

It is because if we considered the population than the expected value would be nearest and there is no need to determine the b0 and b1 value again. But in the case of the sample, the reestimation of the values would be determined again and again

Therefore the correct option is A.

yes

step-by-step explanation:

yes

a)(x-2)^2+(y-1)^2=9
