$$\text { TABLE 11-10 }$$ An Agronomist Wants to Compare the Crop Yield of 3

question 35

Multiple Choice

$$\text { TABLE 11-10 }$$ 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.
$$\begin{array} { l c c l } \underline{\text { Fields }} & \underline{\text { Smith} } & \underline{\text { Walsh }} & \underline{\text { Trevor} } \\1 & 11.1 & 19.0 & 14.6 \\2 & 13.5 & 18.0 & 15.7 \\3 & 15.3 & 19.8 & 16.8 \\4 & 14.6 & 19.6 & 16.7 \\5 & 9.8 & 16.6 & 15.2\end{array}$$
-Referring to Table 11-10, what is the null hypothesis for testing the block effects?

• A) H₀ : µ Field 1 = µ Field 2 = µ Field 3 = µ Field 4 = µ Field 5
• B) H₀ : M Smith = M Walsh = M Trevor
• C) H₀ : µ Smith = µ Walsh = µ Trevor
• D) H₀ : M Field 1 = M Field 2 = M Field 3 = M Field 4 = M Field 5
