Using the data in the file read.dat, test for independence using the data in columns 2, 3, and 10 and the S-PLUS (or R) function pball. Try β = .1, .3, and .5. Comment on any discrepancies.

For the data used in Exercises 8 and 9, test the hypothesis of independence using the function indt. Why might indt find an association not detected by any of the correlations covered in this chapter?
