Question

Suppose You Determine The Estimated Sample Regression Function To Be

Y₁ = 687.51 - 3,212.97 . x_i . You would conclude that

a ) y_i is estimated to equal 687.51 when x_i=0

b) y_i is estimated to increase by 3,212.97 for every one unit increase in x_i.

c) y_i is estimated to decrease by 687.51 for every one unit increase in x_i.

d) y_i is estimated to equal 3,212.97 when x_i=0

Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
