A doctor conducts an experiment to test new treatments for a medical condition. Of the 16 volunteers in the experiment, 4 do not receive any treatment. What percent of the volunteers do not receive any treatment?

Based on the number of volunteers who received no treatment out of the total number, the percentage was 25%.

The percent of volunteers who don't receive treatment are 4 out of a total number of 16.

This number in percentage is:

= Number of volunteers who didn't receive treatment / Total number of volunteers x 100%

Solving would give:

= 4 / 16 x 100%

= 25 %

In conclusion, 25% did not receive treatment.
