A study compared glucose levels among four age groups: toddlers, teenagers, adult, and seniors. The total sample size was n =30 (10 toddlers, 10 teenagers, 5 adult, and 5 seniors). A one-way analysis of variance was used to compare the population mean levels for the four age groups. 1. What are the numerator and denominator degrees of freedom for the F-test? a. 10 for numerator and 30 for denominator. b. None of the choices. c. 4 for numerator and 30 for denominator. d. 3 for numerator and 26 for denominator. e. 3 for numerator and 29 for denominator. 2. The sum of squares for groups is SS Groups = 60. What is the Mean Square for groups (MS Groups)? a. None of the choices. b. 60
