Offspring of fruit flies may have red or brown bodies and normal
wings or short wings. Genetic theory predicts that these traits
will appear in the ratio 9:3:3:1 (9 red, normal: 3 red, short:
3 brown, normal: 1 brown, short). A researcher checks 100 such
flies and finds the distribution of the traits to be 55, 20, 14,
and 11, respectively.
Compute the chi-square statistic. x²=
