Answer:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best
Step-by-step explanation:
The hypothesis in an experiment is the testable explanation given in support of an observer problem. It is a predictive statement that aims at proferring a possible solution to a problem or answer a question asked. The hypothesis must be able to be tested via experimentation as this is one important feature all hypotheses must possess. A hypothesis is usually written in an "IF, THEN" format.
In this question, an investigation is being carried out to know the effect of a certain amount of fertilizer on the growth of orchids in a greenhouse. A possible explanation/hypothesis will be:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best.
This can be accepted or rejected depending on the outcome of the experiment.
