The mean being equal to the range has nothing to do with symmetry.

The proper place to put a percent sign in a range is as follows: 40-60% The percent sign is not used after both ranges (40 and 60) when ranges are used. However, when a percentage range is not being described, such as 40 percent, it is acceptable to place the percent sign immediately following the digits (60 percent; 60%), or a space may be used between the digits and the sign (60 %).
5.9 percent to 8.6 percent

The concentration of carbon dioxide (CO2) in the atmosphere is about 380 parts per million (ppm).
This part of the atmosphere is called the ionosphere. It has the largest concentration of ions because the gases in this area are ionized by Solar Radiation.
Carbon dioxide (CO2) shows the most variation in concentration in the lower atmosphere from place to place and from time to time due to a range of factors such as human activities, vegetation, and industrial processes. These factors impact the local and temporal distribution of CO2 levels, leading to fluctuations in its concentration in the lower atmosphere.
in pH acids range from 0-6.as the highest value is 6 and if the concentration of an acid is 6 it is concentrated as this value drops the concentration drops
No one gas comprises 99% of the atmosphere, but nitrogen (~78.09%) and oxygen (~20.95%) together comprise about 99% of the atmosphere (on a dry basis, i.e. not including water vapor which can range from near 0% to 5%).
The atmosphere acts as a blanket, trapping heat from the sun and preventing it from escaping back into space. This process, known as the greenhouse effect, helps regulate Earth's temperature and keep it within a range that supports life. However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.

Approximately 97 percent of the ozone in the Earth's atmosphere is found in the stratosphere. This region of the atmosphere is located above the troposphere, between about 10 to 50 kilometers above the Earth's surface. Ozone in the stratosphere plays a crucial role in absorbing and filtering out harmful ultraviolet radiation from the sun.
The mean being equal to the range has nothing to do with symmetry.
It is a range from 80-84 percent
This can be called specialization or "niche" marketing.
Divide 6 by 36. It is not an even number. or, one sixth percent.......................
