For 7 and 8, use the following information: We run a regression test, regressing test score on hours studied, and find out that b. = 45 while b₁ = 10. 7. In words, interpret bo. 8. In words, interpret b₁. Which test would you use to answer each of the following research questions? Specify the test type as well as the null and alternative hypotheses. 9. Does life expectancy (in years) differ between smokers and non-smokers? 10. Is there a relationship between US News college ranking (eg 1, 2, 3, 4...) and starting salary after graduation (in dollars)? 11. Is a students GPA when they graduate high school related to their GPA when they graduate college? 12. Is there a relationship between eating breakfast (eating breakfast vs. not eating breakfast) and weight (overweight, underweight, or healthy weight)?
