APBIO-PYNTVG

Fruit flies (Drosophila melanogaster) are attracted to odors found in rotting fruit. A culture of fruit flies is placed in a choice chamber with the following choices: 1 mL of water, 1 mL of sugar water, 1 mL of salt water, and a control with no liquid added, as seen in the image below. After ten minutes, the location of the fruit flies was recorded.

Calculate the Chi-square for this population.
