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 decision made at a 0.005 level of significance implies that all three means are significantly different.

Quizplus · Accepted Answer

The decision at a 0.005 level of significance would require conducting a statistical test, such as ANOVA, to determine if there is a significant difference among the means. The statement does not provide the results of such a test, so we cannot conclude that all three means are significantly different.
