Question

df (numerator) = 3, df (denominator) 18, c 0.05 Fcrit (Use two decimal places.) - df (numerator) = 4, df (denominator) 38, a 0.05 Fcrit (Use two decimal places.) = df (numerator) = 4, df (denominator) 38, o 0.01 (Use two decimal places.) Fcrit What happens to Fcrit as the degrees of freedom increase and alpha is held constant? Fcrit does not change Farit increases. Farit decreases What happens to Fcrit When the degrees of freedom are held constant and alpha is made more stringent? Farit decreases Fcrit does not change Farit increases Find Ferit for the following situations. Use the tables in your textbook or the F Distribution tool here. To use the tool, first set the values for the numerator and denominator degrees of freedom, then move the vertical orange line until the area shown in orange to the right of it equals your given a value.
