Question

It is helpful to form hypotheses because they help focus your investigation on a single idea to be tested. suppose that a farmer wants to determine what the best growing conditions are for almond trees on his farm.

Answer 1

I understand the question here to be "propose a hypothesis that could be useful to the farmer".

Let's see again what the farmer wants to know:" the best growing conditions are for almond trees on his farm. "

Now, there is no way of testing for "the best", but the farmer could make some variations and check their influence on the farm.

The hypothesis have to phrased as statements so for example:

1. Trees that receive more water, are taller
2. Trees that receive more water, produce more almonds
3. Trees that receive more water, produce bigger almonds.
