A randomized block design is used to compare four treatments in eight blocks.

a. Use the Friedman Fr-test to detect differences in location among the four treatment distributions. Test using α =.05.
b. Find the approximate p-value for the test in part a.
c. Perform an analysis of variance and give the ANOVA table for the analysis.
d. Give the value of the F statistic for testing the equality of the four treatment means.
e. Give the approximate p-value for the F statistic in part d.
f. Compare the p-values for the tests in parts a and d, and explain the practical implications of the comparison.
