Suppose that we have conducted a Simple Linear Regression for Exam 1 score by Homework 1 score and found the predicted line equation to be y_hat = 58.52 + 2.19x, where x represents Homework 1 score and y represents Exam 1 score. What Exam 1 score can a student who did not submit the homework expect to receive based on this predicted line equation? Group of answer choices y_hat 117.04 x 2.19 58.52

Respuesta :

Answer:

58.52

Step-by-step explanation:

The predicted regression equation for predicting Exam 1 score is

y_hat=58.52+2.19x.

We have to find the predicted exam score 1 for student who did not submit homework. If the student did not submit homework 1 score then the homework 1 score will be zero. So,

y_hat=58.52+2.19(0)

y_hat=58.52.

Thus, the predicted exam score 1 for student who did not submit homework 1 score is 58.52.
