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)
