In a study by researchers at the University of Maryland, the body temperatures of 106 individuals were measured; the mean for the sample was 98.20◦F. It is commonly believed that the mean body temperature is 98.60◦F. The difference between the sample mean and the accepted value is significant at the 0.05 level.

Ответ:
Energy does not disappear, the energy is transformed from one form into another form. When a car stereo is turned on, the car radio converts radio waves to electrical energy, next the electrical energy in transformed in sound. It means when someone turn on a radio we have electrical energy, which is transformed into electrical energy and then into energy acoustic.
The complete sequence of energy is:
First transmission sound energy is converted into mechanical energy then electrical energy in the microphone, next into radio waves that is electromagnetic energy. The aerials convert electromagnetic energy in electrical energy and next in magnetic and mechanical energy and finally in sound energy.
