d. it is the value of the explanatory variable for the ith observation in the population.
e. it is the​ y-intercept of the population regression line.

Answer 1

We are looking at the
`y_(i) = \beta_(0) + \beta_(1) * x_(i) + e`, where
`y_(i)` is an explained, dependent variable and it is the value of explanatory variable for the ith observation in population. So that, the correct answer is D.
