Question

a farmer wants to find out the average number of apples produced by the apple trees in his orchard. which could be a sample of the population? all the trees on the farmer’s land all the apple trees in the farmer’s orchard some of the apple trees in the farmer’s orchard one apple tree in the farmer’s orchard

Explanation:

The population here is the apple trees in the farmer's orchard (since we care about apples from these trees). A sample is a subset of the population.

• Option 1: "all the trees on the farmer’s land" includes non - apple trees, so not the population's sample.
• Option 2: "all the apple trees in the farmer’s orchard" is the entire population, not a sample.
• Option 3: "some of the apple trees in the farmer’s orchard" is a subset of the population (apple trees in orchard) and can be used as a sample to estimate the average apples per apple tree.
• Option 4: "one apple tree in the farmer’s orchard" is a sample but a very small one, but the question is about which "could be" a sample. However, "some" is more representative of a sample (as a sample is usually more than one but less than the whole population in most cases for estimation). But among the options, "some of the apple trees in the farmer’s orchard" is a valid sample of the population (apple trees in orchard).

Answer:

C. some of the apple trees in the farmer’s orchard (assuming the options are labeled A: all the trees on the farmer’s land, B: all the apple trees in the farmer’s orchard, C: some of the apple trees in the farmer’s orchard, D: one apple tree in the farmer’s orchard)
