In corn plants, Zea mays, purple kernels are dominant to yellow kernels, and smooth kernels are dominant to wrinkled kernels. In a dihybrid cross where a 9:3:3:1 ratio is expected, the following data were collected:
purple and smooth: 223
purple and wrinkled: 84
yellow and smooth: 89
yellow and wrinkled: 33
Calculate the chi square value for the data. Round to the nearest hundredth.
