The researcher was specifically interested in determining whether those with a grade school, high school, or college education were more likely to drink beer, wine, or hard liquor.

She estimated that 20 percent of the population of interest had a college education, 70 percent a high school education, and 10 percent only a grade school education, and further that 40 percent of the population preferred beer, 40 percent wine, and 20 percent hard liquor. She desired a minimum of 20 observations per cell on which to base percentages. How large a sample should she select?
 a. 200
  b. 250
