Similar to the addition of SS"s and degrees of freedom in an ANOVA, 2 and degrees of freedom for independent populations can be added together.

Similar to the addition of SS"s and degrees of freedom in an ANOVA, 2 and degrees of freedom for independent populations can be added together. Asking if any of the populations deviate from our hypothesis of simple dominance. Other questions we might want to ask about pooling similar populations: Do all the subpopulations have the same ratio of yellow to green seeds? Does the average ratio deviate from our hypothesized ratio?
