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, the randomized block F test is valid only if the population of crop yields is normally distributed for the 3 varieties.

Quizplus · Accepted Answer

The validity of the randomized block F test is based on the assumption of normality of the population of crop yields for each variety. Therefore, the statement is true. The randomized block F test assumes normality of the population of crop yields for the 3 varieties.
