Folacin is the only B vitamin present in any significant amount in tea, and recent advances in assay methods have made accurate determination of folacin content feasible. Consider the accompanying data on folacin content for randomly selected specimens of the four leading brands of green tea. Brand Observations 1 8.0 6.3 6.7 8.7 9.0 10.2 9.7 2 5.8 7.6 9.9 6.2 8.5 3 6.9 7.6 5.1 7.5 5.4 6.2 4 6.5 7.2 8.0 4.6 5.1 4.1 Does this data suggest that true average folacin content is the same for all brands? Carry out a test using a =. 05via the ANOVA method.
