TABLE 12-2 An Agronomist Wants to Compare the Crop Yield of 3

Multiple Choice

TABLE 12-2
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 Table 12-2, the null hypothesis for the Friedman rank test is

A) H₀: μFᵢₑld₁ = μFᵢₑld₂ = μFᵢₑld₃ = μFᵢₑld₄ = μFᵢₑld₅.
B) H₀: μSmᵢth = μWₐlsh = μTᵣₑᵥₒᵣ.
C) H₀: MFᵢₑld₁ = MFᵢₑld₂ = MFᵢₑld₃ = MFᵢₑld₄ = MFᵢₑld₅.
D) H₀: MSmᵢth = MWₐlsh = MTᵣₑᵥₒᵣ.
