Question

Please i need help with question 1 & 2 below. Thanks

QUESTION 1 For simple linear regression, we have one regression coefficient for the y intercept and one regression coefficient for the slope. True False QUESTION 2 What is a residual The difference between the coefficient for the y intercept and the coefficient for the slope. The difference between the real value for y and the fitted value for y. The difference between the largest value for x and the smallest value for X. The difference between the largest value for y and the smallest value for y.

Answer 1

Solution:

Question 1)

Simple linear regression equation is given by:

y = bo + b12

where

$b_{0}$ is y intercept

$b_{1}$ is slope.

Thus given statement is TRUE.

Question 2)

Residual is defined as: the difference between actual value ( y) and estimated ( fitted) value (y).

It is given by:

R; = yi - 9

Thus correct option is:

The difference between the real value for y and the fitted value for y
