34                    51                        80

What is the calculated chi-squared value?

(A) We assume that the proportion of green should be same for all three, i.e. p = 1/3

total frequency = 30+80121 = 231

Expected value for West Green = total frequency*proportion = 231*(1/3) = 77

(B) We assume that the proportion of green should be same for all three, i.e. p = 1/3

total frequency = 34+51+80 = 165

Expected value for each Green = total frequency*proportion = 165*(1/3) = 55
