due in class, Tuesday February 18

You must SHOW ALL WORK for full credit (except for things computed entirely in R, of course). Please staple your assignment if it is more than one page.

Required problems:

1) 9.13 (p. 313)
2) 9.31 parts (a) and (b/c) only, and you can combine parts (b) and (c), i.e., you can use a p-value to answer part (b) (but you should still interpret it in part (c)) (p. 319)
3) 9.55 (you may use either a .01 or .05 level, just use the same level for parts (a) and (b)) (p. 329)
4) 9.93 parts (a) and (b) (p. 341)
5) 11.5 (p. 405)

Optional problems:

6) 9.93 parts (c)-(e) (p. 341)
7) 9.94 parts (a) and (b) (p. 341)
8) 10.31 (p. 370) You can combine parts (a) and (c) (i.e., you can use the p-value to answer part (a)), and you can skip part (b).

If you have the 9th edition, the corresponding problems are:
1) 9.13 (p. 300-1), 2) 9.31 (306), 3) 9.60 (316), 4) 9.98 parts (a) and (b) (328), 5) 11.5 (401), 6) 9.98 (328), 7) 9.99 parts (a) and (b) (328), 8) not in the 9th ed., but 10.36 (360) is comparable
