Ho2: Spirobranchus giganteus have equal frequencies of both bright and dark coloration among the four coral species Spirobranchus giganteus inhabits.

Ha2: Spirobranchus giganteus do not have equal frequencies of both bright and dark coloration among the four coral species Spirobranchus giganteus inhabits.

Accept null hypothesis

P=0.633 so cannot reject null hypothesis. Therefore, Spirobranchus giganteus have equal frequencies of both bright and dark coloration among the four coral species Spirobranchus giganteus inhabits when alpha = .05. The data were grouped as shown below.
