On a television talk show, a guest claims that people who exercise vigorously for 15 minutes or more every day are able to solve math problems more rapidly than

people who have no vigorous exercise in their daily routine.

Describe a controlled experiment that could be conducted to test this claim. In

your description be sure to:

• state the purpose of the experiment

• state why the sample to be used should be large

• describe how the experimental group will be treated and how the control

group will be treated

• state the specific data to be collected during the experiment

• state one way to determine if the results support the claim

In the explanation box.

Explanation:

Purpose: discover if daily exercise would help or not on the ability to solve math problems.

We need a large sample to have various people with different cognitive abilities.

The experimental group will have to exercise at least 15 minutes a day, and the control group will go on with their normal lives, we will have to put a math exam with the same difficulty at the end and at the beginning of the experiment to see if the experimental group and the control group perform significantly better.

The data would be the two different math tests and the amount of exercise that both groups do daily.

If the experiment group performs significantly better than the control group in the final results we could support that the exercise helps perform better at math.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
