A researcher was conducting an investigation to determine if level of education affected a person's consumption of alcoholic beverages. 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. To investigate the question the researcher planned to cross classify these three education levels of respondents against their preferences for each of these beverages. 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
  c. 400
  d. 500
