Question

biostatistics course, the chapter of probability

Coughlin et al. examined the breast and cervical sereening practices of Hispanic and non-
Hispanic women in counties that approximate the U.S. southern border region. The study

years or older conducted in 1999 and 2000. The table below reports the number of
observations of Hispanic and non-Hispanic women who had received a mammogram in the
past 2 years cross-classified with marital status.
