True/False

SCENARIO 10-4
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds.She plants 15 fields,
5 with each variety.She then measures the crop yield in bushels per acre.Treating this as a completely randomized design, the results are presented in the table that follows. $\begin{array}{rrrr}\text { Trial}&\text { Smith}&\text { Walsh}&\text { Trevor }\\1 & 11.1 & 19.0 & 14.6 \\2 & 13.5 & 18.0 & 15.7 \\3 & 15.3 & 19.8 & 16.8 \\4 & 14.6 & 19.6 & 16.7 \\5 & 9.8 & 16.6 & 15.2\end{array}$
-Referring to SCENARIO 10-4, based on the Tukey-Kramer procedure with an overall level of significance of 0.01, the agronomist would decide that there is a significant difference between the crop yield of Smith and Trevor seeds.
