Homework 8


due in class, Tuesday March 9



Required problems:

1) 15.42 (p. 627) and note that the data file is tab-delimited, so to read it in use read.table with header=T and sep="\t"; there are two missing observations, so you should probably just remove those two cars and work with the remaining 104 cars
2) 18.6 part (a) (pp. 733-4)

Optional problem:

3) 18.16 (pp. 740-1)

If you have the 9th edition, the corresponding problems are:
1) 15.44 (p. 621) but use the AUTO2000 data file from the class website and see the note above, 2) 18.6 (730-1) part (a); Optional: 3) not in 9th ed, but 18.17 parts (a-b) (p. 736) is similar
