In a study of crop rotation techniques,agricultural researchers are interested in making general statements concerning the effectiveness of a given technique for all corn fields in the state of Kansas.Using a cluster technique,they randomly choose 30 farms from across the state for their study.Some of the chosen farms are randomly selected to use the rotation technique whereas others are not.In this study,the population is best described as:
A) 30 farms chosen from across the state.
B) all corn fields in the state of Kansas.
C) the effectiveness of crop rotation.
D) whether the rotation technique was used or not.

Question

Quizplus · Accepted Answer

The population of interest in this study is all corn fields in the state of Kansas, as the researchers aim to make general statements about the effectiveness of crop rotation for these fields. The 30 farms chosen from across the state are a sample of this population. The use of the cluster technique allows for random sampling across different regions of the state, which helps to ensure the sample is representative of the population. The choice of whether or not to use the rotation technique is a variable being tested in the study, but it does not define the population.
