Question

For the following question, which is the best hypothesis "Does exposure to radon (a source of natural radiation) in your home cause an increased risk of cancer?"
Everyone who is exposed to radon will die from cancer.

People should not risk exposure to radon!

Cancer may be caused by many different factors, including exposure to radiation, chemicals and too much stress in a person's life.

I am immune to cancer because there is no history of cancer in my family.

People who have been exposed to radon have an increased rate of cancer, as compared to people who have not been exposed.

Answer 1

Answer:

People who have been exposed to radon have an increased rate of cancer, as compared to people who have not been exposed.

Explanation:

Hypothesis of an experiment is a testable explanation or a suggested solution that aims to answer a question asked or solve an observed problem. The hypothesis must be able to be tested via experimentation and must not be true. A good hypothesis should include the independent and dependent variables in it.

For the problem/question asked in this experiment that: Does exposure to radon (a source of natural radiation) in your home cause an increased risk of cancer?"

The best hypothesis that provides a testable answer to this question is: People who have been exposed to radon have an increased rate of cancer, as compared to people who have not been exposed.

From the above hypothesis, we can see that it contains the independent variable, which is exposure to radon, and the dependent variable, which is cancer rate
