SCENARIO 11-6
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds.She plants all 3 varieties of the seeds on each of 5 different patches of fields.She then measures the crop yield in bushels per acre.Treating this as a randomized block design,the results are presented in the table that follows.

-Referring to Scenario 11-6,based on the Tukey multiple comparison procedure with an overall level of significance of 0.01,the agronomist would decide that there is a significant difference between the crop yield of Walsh and Trevor seeds.

Quizplus · Accepted Answer

From the table, the difference between the crop yield of Walsh and Trevor seeds is 24.2, which is greater than the Tukey range of 9.217. Therefore, the agronomist would reject the null hypothesis and conclude that there is a significant difference between the crop yield of Walsh and Trevor seeds.
