9. The inorganic arsenic levels in 4 types of white rice (jasmine, basmati, sushi, Bombay) were examined. Independent, random samples were taken from each type of rice and the inorganic arsenic levels recorded. Assume all 4 populations arsenic levels are normally distributed. The data, in ppb, and Anova table are given below:
