Question

s samples of each of our types of cereal grain grown in a certain region were analyzed to determine am n content, resulting in the following data ㎍/g Note: If you want to use R this data has been set up so you may copy ıt d ec y into R Wheat- 5.1, 4.4, 6.1, 6.2, 6.6, 5.7) Sarley- 6.5, 7.9, 6.0, 7.5, 5.8, 5.7) Maize- 5.8, 4.7, 6.5, 5.0, 6.1, 5.3) Oats- 8.2, 6.0, 7.7, 6.9, 5.4, 7.2 In this example I What are the individual xwheat and J = group means, x? Barley π Naize What is the grand mean X? Calculate the mean squared treatment. (Round your answer to two decimal places.) Calculate the variance for each group, Note: These can be done in R using the var) command. whest s-Berley = Osts Calculate the mean squared error. (Round your answer to two decimal places.) Does this data suggest that at least two of the grains differ with respect to true average thiamin oontent? Use a level α-0.05 test based on the P-value method. State the appropriate hypotheses. H: all four 's are unequal t least two μ!'s are unequal : H: at least two us are equal : all four μ/s are equal Compute the test statistic value.(Round your answer to two decimal places.) MSE

Answer 1

(please round the numbers to the required number of decimal places.)


What can be said about the p-value? 0.010 < p-value < 0.050.
State the conclusion? 2nd option is correct.
What should we do next to compare the individual means? 4th option is correct.
