4. Population regression line.

Step by step solution

01

Given information

The four conditions required for making regression inferences

02

Explanation

The following are the requirements for making regression inferences:

1. Independent observations: The responses to variable observations are unrelated to one another.

2. Equal standard deviations: The conditional standard deviations of the response variable are the same for all values of the predictor variable.

3. Normal populations: For each value of the predictor variable, the conditional distribution of the responder variable is a normal distribution.

4. Population regression line: There are constants 尾0and 尾1such that the conditional mean of the response variables is 尾0+尾1xfor each value of x for the predictor variable.
