According to a theory, four categories of strawberries are supposed to occur in the ratio 9:3:3:1. For these four categories, 124, 30, 43 and 11 were counted, respectively. Are these compatible with the theory?Let

.

Work so far-

124+30+43+11=208

Expected values are therefore 117, 39, 39, 13 for the ratio 9:3:3:1

(4 columns - 1)=3 degrees of freedom

I calculated the Chi-test statistic by doing (124-117)^2/117+....+(11-13)^2/13 and got 3.21, but I am not sure what to compare it to or what to do with the

. Thanks for your help!
