A truck Company wants to find out if their drivers are still alert after driving long hours so, they give a test for alertness to two groups of drivers they give the test to 330 drivers who have just finished driving four hours or less and they give the test to 215 drivers who have just finished driving eight hours or more. Results are below. Drove 4 hours or less: passed= 250. Failed=80 Drove 8 hours or more: passed= 140, failed=75 Is there a relationship between hours of driving and alertness? Do a test for independence. Test at 1% level of significance. Thank you
