question 26

Multiple Choice

Instruction 11-8
An agronomist wants to compare the crop yield of three varieties of chickpea seeds.She plants all three varieties of the seeds on each of five different patches of fields.She then measures the crop yield in bushels per acre.Treating this as a randomised block design,the results are presented in the table that follows.
$$\begin{array} { | l | l | l | l | } \hline \text { Fields } & \text { Smith } & \text { Walsh } & \text { Trevor } \\\hline 1 & 11.1 & 19.0 & 14.6 \\\hline 2 & 13.5 & 18.0 & 15.7 \\\hline 3 & 15.3 & 19.8 & 16.8 \\\hline 4 & 14.6 & 19.6 & 16.7 \\\hline 5 & 9.8 & 16.6 & 15.2 \\\hline\end{array}$$
-Referring to Instruction 11-8,the null hypothesis for the randomised block F test for the difference in the means is

• A)H₀: M_Smith = M_Walsh = M_Trevor.
• B)H₀: ?_Smith = ?_Walsh = ?_Trevor.
• C)H₀: ?_{Field 1} = ?_{Field 2} = ?_{Field 3} = ?_{Field 4} = ?_{Field 5.}
• D)H₀: M_{Field 1} = M_{Field 2} = M_{Field 3} = M_{Field 4} = M_{Field 5.}
