Solution
Population refers to the aggregate or the total items to be studied for an investigation. So, the population here is 200 farms.
The sample is a subset of the population. In other words, a small set selected from the population for the statistical study is referred to as the sample population.
Out of 200 farms, only 50 farms are selected for the survey; therefore, the sample population is 50 farms.
