Does this data suggest that at least two of the grains differ with respect to true average thiamin content? Use a level a = 0.05 test based on the P-value method. State the appropriate hypotheses. O Ho: H1 = M2 = M3 = 14 Ha: all four w/'s are unequal O Ho: M1 = 12 = M3 = M4 Ha: at least two uf's are unequal O Ho: M1 = 12 = 13 = 14 Ha: all four uf's are equal O Ho: M1 # 12 # 13 # 14 Ha: at least two u/'s are equal Compute the test statistic value. (Round your answer to two decimal places.) MST = MSE What can be said about the P-value for the test? Use R to find your p-value using the CDF of the f distribution pf(). Recall the p-value from an F test is always the area to the right of the F test statistic. Example: 1-pf(f test statistic, df1, df2) O P-value > 0.100 O 0.050
