Answer:

Dr. Alexander is a scientist who studies a certain type of fly. In his studies, he came across information that says that the fly doesn't need any calcium in its diet. This question interests him because he doesn't think it is true. He decides to create an experiment that will test whether this question is true. His hypothesis is that a fly will not live without calcium in its diet.

Dr. Alexander believes that flies must have calcium in their diet. In one of Dr. Alexander’s experiments, he feeds one hundred flies a normal diet with calcium. Then he feeds one hundred more flies a diet without calcium. Over seven days he records the following data:

Fed Calcium Not Fed Calcium

Flies alive before test 100 100

Flies alive after test 92 10

Based off the data above what would be a valid conclusion Dr. Alexander could make?
