PROBLEMS # 2, #4 & #6: Basic definitions and reasons for using this test.
PROBLEM # 10: See if you can apply this analysis.
PROBLEM #17: This has all the calculations involved. Can you find the critical F-value from the Table? The p-value can also be approximated from that Table. (Find an F-Table that you like on line)
The Table asked for has these headings: SOURCE (with these categories down the side: age, time, age x time, error and total), then continuing across the top: df, SSQ, MS, F and P. Go ahead and fill it in.

PROBLEMS #1 through 8 (count as ONE problem): This is all about knowing the why and when about this test.
PROBLEMS #9 through 15 (count as ONE problem): This involves working a basic F-test problem. Can you find the critical F-value and compare the test statistic to it to see if we accept or reject (you pick an alpha). You also can approximate the p-value from the table (find table on web if necessary).
BONUS: For a 1 point bonus, work problem #71 and see if you have this concept (F-test) down.
