Question

Table 9.1

	Number of Prey Captured Per Trial
Color of Prey											Total Trials 1-10	% of Total
Pink											21	26%
Red											8	10%
White											17	21%
Yellow											20	25.3%
Green											13	16.4%

Table 9.1: Chi-square Table

Paper clip color	Pink	Red	White	Yellow	Green	Total
Observed number (O)	21	8	17	20	13	79
Expected number (E)
(O-E)
(O-E)2
(O-E)2 / E

How do I find the expected value?

Answer 1

Null hypothesis: The number of prey captured should be found in equal proprtion. That's why the expected number of each type should be (1/5) ×79= 15. 8
