Suppose an experiment is designed to test the durability of batteries in different conditions. All of the batteries tested
are double-A (AA) Brand X. All sets of batteries are preconditioned in different environmental conditions for exactly 168
hours (1 week)
Set 1: O'C (freezing point of water)
Set 2: 24°C (approximately room temperature)
Set 3: 37°C (approximately body temperature)
The batteries are then continuously used to power identical mechanical drummer toys. As long as the toy keeps
drumming the battery is considered functional. The drumming time for each toy is measured as an indication of battery
durability.
Which of the following would be the best hypothesis for the above experiment?
Battery life is effected by the environmental temperature at which it is stored
If batteries are stored at cooler temperatures, they will be able to power mechanical devices for longer periods of time
If batteries are stored at cooler temperatures, they will deliver stronger levels of power to mechanical devices.
