Exercise 14-7. Suppose that you are a research assistant for a political science professor. The professor is working on a research project on immigration. The professor has asked you to examine the regression results in table 14-2 and answer the questions that follow.

a. Compute the observed t for the regression coefficient.

b. What are the degrees of freedom for testing the significance of the regression coefficient?

c. What is the critical t at the .01 level for a one-tailed test?

d. Is the relationship between the independent and dependent variable statistically significant? How do you know?

e. Do you accept or reject the hypothesis that countries with larger foreign-born populations attract more immigration?

f. What percentage of the variation in immigration is "explained" by variation in foreign-born population?
