I have another question on my stats homework, relating to degrees of freedom. However, I have NO idea how this question even relates to degrees of freedom! I understand degrees of freedom on their own, i.e. how when calculating standard deviation you divide by df instead of total n because the centered scores always equal out to zero, but I don't get how that relates to this question. Is the professor just trying to throw us off with irrelevant info? Is the answer simply 10?
Last Saturday, Karl went to a party at a friend’s house. His friend had ordered 4 medium (8 slice) pizzas from Flying Tomato Pizza. There was a “Veggie” pizza (with Mushroom, Green Pepper, Tomato, & Onion), a “Greek” pizza (with Black Olives, Tomato, Onion, & Feta Cheese), and two “Meat Lovers” pizzas (with Pepperoni, Ham, Bacon, & Italian Sausage).
Karl is vegetarian, and when he goes to get a slice of pizza, there remain 6 slices of the “Veggie” pizza, 4 slices of the “Greek” pizza, and 9 slices of the “Meat Lovers” pizzas. How many degrees of freedom does Karl have in picking his slice of pizza?
