Question

Given the least squares regression equation,  = 1202 + 1,133X,when X = 3,what does  equal?
A)5,734

Quizplus · Accepted Answer

When X = 3, we can substitute into the regression equation:
11eac02f_e47b_dd87_a79a_d772151fe6a0_TB7522_11 = 1202 + 1,133(3) = 3,601
Therefore, the answer is C, 4,601, which is closest to 3,601. Answer choices A, B, and D are significantly further away from 3,601.
