B. Test for the significance of the correlation using a two-tailed test at the .05 level.

C. Show the scatterplot for the data.

D. Determine the coefficient of determination and explain what this means.

E. Determine the coefficient of alienation (nondetermination) and explain what this means.

F. Explain to a friend what this correlation coefficient tells you about the relationship between fathers' high school GPA and children's social skills.

G. Explain to your friend what this correlation does not tell you about the relationship between these two variables.  Suggest a third variable that may be a work here.
