Regression Equation for Males Eating Junk Food

1. Figure out the regression equation for males based on what they spend on junk food and their weight. The weight is the independent variable. Do we have a correlation?
2. Figure out the regression equation for females based on what they spend on junk food and their weight. Do we have a correlation?
Note: For the first part you need to calculate the regression coefficients and place them in the regression equation. You should end up with two equations, one for males and one for females. It should look like
Y' = mX + b
For the second part you need to find the correlation coefficient ( r ) for males and correlation coefficient ( r ) for females. Student test to prove correlation will assist you in the decision and use the level of significance of .05 to tell me if there is a relationship between the variables.
