Correct Answer Explanation
The sample size is 50 — the number of farms actually surveyed. The population is 200 — the total number of farms in the village.
Key Distinction:
- Population: The entire group under study — here, all 200 farms in the village.
- Sample: The subset selected for study — here, the 50 farms surveyed.
- Sample size = 50/200 = 25% of the population.
- In the given example, 50% of the 50 farms (i.e., 25 farms) grew only wheat.
- This data from the sample is used to make inferences about all 200 farms in the village.
