Answer:

A. The first equation is for sample​ data; the second equation is for a population.

Step-by-step explanation:

The first equation is y = b_0 + b_1x , this is the equation for sample data as the intercept (b_0) and the slope parameter(b_1)  both are calculated then we have got this and these values are not taken as given.

The Second equation is y = \beta _0 +\beta _1x , this is the equation for population data as we can't calculate these \beta _0 and \beta _1 as we take these values as given and also we do testing for \beta parameter using t test and it is sure that testing is always done on population data not on sample data.
