In order to perform a simple linear regression, the residuals need to follow a specific pattern across values of the independent variable.
True or false
Homework Answers
In order to perform a simple linear regression, the residuals need to follow a specific pattern across values of the independent variable.
Answer:
False
Explanation:
The above statement is false because the residuals need not to follow a specific pattern across values of the independent variable in order to perform a simple linear regression. Most of the time residual plot shows a fairly random pattern. If the residual plot shows the random pattern, then we can say that linear model is good fit to the data.

For simple linear regression, suppose that we examine a residual plot and find that the residuals are generally more-dispersed at lower levels of the explanatory variable. True or False: This suggests that one of the assumptions for simple linear regression is violated.

Answer both questions please true or false 16. The slope of the simple linear regression equation represents the average change in the value of the dependent variable per unit change in the independent variable (X). True/False 19. When using simple regression analysis, if there is a strong correlation between the independent and dependent variable, then we can conclude that an increase in the value of the independent variable causes an increase in the value of the dependent variable.

The standard deviation of the sampling distribution of the sample mean is the same as the population standard deviation. True False 3.
