A student investigated whether ants dig more tunnels in the light or in the dark. She noticed that she sees more ants during the daytime than at night and thought that ants would dig more tunnels during the daytime. Ten ant colonies were set up in ant farms with the same number and type of ants per ant farm. The same amount of food was given to each colony, and the colonies were at the same temperature. Five of the colonies were exposed to normal room light and five were covered with black construction paper so they did not receive light. Every other day for three weeks the length of the tunnels was measured in millimeters using a string and a ruler. Averages for the light and dark groups for each measured were then computed. The averages are listed in the following chart.

What would be a scientific if then statement?
