Can swimmers hold their breath longer that people who don't swim. what is the hypothesis?

A hypothesis is a statement, not a question.

Can swimmers hold their breath longer that people who don't swim ?

I have no idea.  What do you think ?  The hypothesis is what you think.

I see three possibilities here:

1).  Swimmers can hold their breath longer that non-swimmers.

2).  People who don't swim can hold their breath longer than swimmers.

3).  Average swimmers and average non-swimmers can generally hold their breath for the same length of time.

These are three possible hypotheses.  There may be others that I didn't think of.

What do you think ?  Once you decide what YOU think, you have a hypothesis.  Your next job is to set up some kind of test or experiment to find out whether your hypothesis is true or not.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
