Example 10.5.4 Out of 160 offsprings obtained due to cross-breeding bet- ween guinea pigs, 102 are red, 24 are black and 34 are white. According to a genetic model, the probabilities of red, black and white are 9/16, 3/16, 1/4, respectively. Test at 5% significance level if the data is consistent with the model. (For 2 degrees of freedom, P(x² > 5.99) = 0.05.) %3!
