Answer:
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.
