1. When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are

placed in a 2-choice choice chamber. A cotton ball dampened with distilled

water is placed in Chamber A; A dry cotton ball is placed in Chamber B.

After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found

in Chamber A. Perform the chi-squared test to determine if the distribution

of isopods is significant or due to random chance. (3 points)
