8 1 point Question at position 8 A researcher conducts an ANOVA to compare bill length across three types of penguins -- her data include 50 Gentoo penguins, 50 Adlie penguins, and 50 Chinstrap penguins. What is the degrees of freedom for the between groups and within groups variability respectively?
