Instruction 19-6
an Agronomist Wants to Compare the Crop Yield

question 49

Short Answer

Instruction 19-6
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.
$$\begin{array} { | c | c | c | c | } \hline \text { Fields } & \text { Smith } & \text { Walsh } & \text { Trevor } \\\hline 1 & 11.1 & 19.0 & 14.6 \\\hline2 & 13.5 & 18.0 & 15.7 \\\hline 3 & 15.3 & 19.8 & 16.8 \\\hline 4 & 14.6 & 19.6 & 16.7 \\\hline 5& 9.8 & 16.6 & 15.2 \\\hline\end{array}$$ Below is the Minitab output of the Friedman rank test:
Friectman Test Yedd versus Varieties Felds
Friedmantest for Yield by Varieties blocked by Fields $S = 10.00 D F = 2 P = 0.007$

$\begin{array} { l l l l } \text { Varieties } & N & \text { EstMedian } & \text { Sum of Ranks } \\ & & & \\ \text { Smith } & 5 & 13.500 & 5.0 \\ \text { Trevor } & 5 & 15.667 & 10.0 \\ \text { Walsh } & 5 & 18.533 & 15.0 \end{array}$

$\text { Grand median }=15.900$

-Referring to Instruction 19-6,what is the critical value of the Friedman rank test for the difference in the medians at a level of significance of 0.01?

Grasp the concept of cross elasticity of demand and how it relates to substitutes and complements.

Recognize how price elasticity of supply is determined and its implications for production shifts.

Distinguish between the different types of goods based on income elasticity (normal, inferior, luxury, necessity).

Understand how elasticity concepts apply to real-world economic decision-making and policy.
