Based on Public Demand, Price for Seeds, and Average Yield $\alpha$

question 24

Essay

Based on public demand, price for seeds, and average yield, a farmer must choose which variety of wheat to grow. In the first step toward making a decision, the farmer planted eight test plots each with three varieties of wheat. The recorded yields (in kilograms per plot) were used in an analysis of variance. Use the output below from the analysis of variance to test the null hypothesis of no difference among the mean yields of the three varieties of wheat. Use $\alpha$ = 0.005 to draw conclusions.
