A regression line describes the relationship between the dependent and independent variables and can be used to estimate specific points for x or y. For example, if y = 4.67x + 12.89, and y = 10.87, x would equal
[1] 0.43
[2] -0.43
[3] 12.89
[4] 63.65
Homework Answers
Answer:
2). - 0.43
Explanation:
y = 4.67x + 12.89
10.87= 4.67x + 12.89
4.67x = 10.87 - 12.89
4.67x = -2.02
x = -2.02/4.67
x = -0.43

The equation of the regression line between two variables x (independent variable) and y (dependent variable) is given by y-hat = -3x + 2; and the correlation coefficient is r = -.95. The possible x-values range from 1 to 10. Which of the following statements are correct? I. The variable y is strongly positive correlated to the variable x. II. The variable y is strongly negative correlated to the variable x. III. If x = 5, one would predict that...

Question 6A regression line can be used to determine the strength of a relationship. determine if there is a cause and effect relationship. predict Y for any X value. establish if a relationship is linear. Question 7 If the correlation coefficient R between two variables is ,it is expected that the slope of the regression line will be positive; positive positive; large negative; small positive; negative Question 8 If the slope of the simple regression line is .12, then the Pearson correlation coefficient r is expected to be positive negative small large

Regression and Multicollinearity When multiple independent variables are used to predict a dependent variable in multiple regression, multicollinearity among the independent variables is often a concern. What is the main problem caused by high multicollinearity among the independent variables in a multiple regression equation? Can you still achieve a high r for your regression equation if multicollinearity is present in your data?
