A microbiologist studying bacteria hypothesizes that a colony will double in size overnight if she increases the temperature of their surroundings
by 10°C from 25°C to 35°C.
She increases the temperature before leaving for the day and checks the
colony the next morning. She observes that the size of the colony is the
same size as it was the day before, despite the change in temperature.
a) Is the microbiologist's hypothesis testable? Why or why not?
