Instruction 11-9
An agronomist wants to compare the crop yield of three varieties of chickpea seeds.She plants 15 fields,five with each variety.She then measures the crop yield in bushels per acre.Treating this as a completely randomised design,the results are presented in the table that follows.
$\begin{array}{rrrr}
\text {Trial }&\text {Smith }&\text { Walsh}&\text {Trevor }\
\hline1 & 11.1 & 19.0 & 14.6 \
2 & 13.5 & 18.0 & 15.7 \
3 & 15.3 & 19.8 & 16.8 \
4 & 14.6 & 19.6 & 16.7 \
5 & 9.8 & 16.6 & 15.2
\end{array}$
-Referring to Instruction 11-9,using an overall level of significance of 0.01,the critical value of the Studentised range Q used in calculating the critical range for the Tukey-Kramer procedure is ________.
