Review the experimental question and hypothesis. Which statement best explains why the hypothesis is testable?
Question:
How does the amount of water individuals drink everyday affect the number of facial blemishes they receive every month?
Hypothesis:
If the amount of water people drink everyday affects the concentration of certain hormones in their blood, then increasing the amount of water consumed daily will decrease the number of facial blemishes they receive each month.
The hypothesis includes an explanation and makes a prediction.
The hypothesis is written using an "If …, then …" format.
The hypothesis includes both an independent variable and a dependent variable.
The hypothesis can be used to accurately explain observable facts.
I think the answer should be that there is an if -- then way the statement is worded. Quite often if then statements are used in this kind of experiment. Beyond that I can't make any comment. I don't know that it truly is testable, but it sounds like it should be.
