We asked subjects how many siblings they had and what their average test score was in their Geography class. Draw a scatter plot showing the relationship between sibs and test scores. Test the degree of association between these two variables. If significant, do the regression analysis, state the regression equation, draw the regression line on your scatter plot, and write a results statement describing your findings.
