Six samples of each of four types of cereal grain grown in a certain region were analyzed to determine thiamin content, resulting in the following data (µg/g): Note: If you want to use R this data has been set up so you may copy it directly into R. Wheat=c( 5.3, 4.6, 5.9, 6.2, 6.8, 5.8) Barley=c( 6.5, 8.0, 6.2, 7.5, 6.0, 5.6) Maize=c( 5.9, 4.6, 6.4, 4.9, 6.1, 5.3) Oats = c( 8.3, 6.0, 7.7, 7.0, 5.6, 7.2)
