In 1. Numerator df: k-1= 4,
n=5, so N= k*n= 25, so denominator df(N-k)= 25-5= 20
So critical value is at F4,20= 2.866 at alpha=0.05
2. Numerator df=11
Denominator df= 48-12= 36
So critical values is at F11,36 = 2.791 at alpha=0.01
3. Numerator df= 1
Denominator df= 10*2 - 2= 18
So F1,18 = 4.414 at alpha=0.05
4. Numerator df= 5
Denominator df= 2*6-6= 6
So F5,6= 8.746 at alpha=0.01
5. Numerator df= 7
Denominator df= 24-8 = 16
So F7,16 = 2.657 at alpha= 0.05

QUESTION 1 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 4 groups (J = 4), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places. QUESTION 2 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 6 groups (J = 6), what would...
Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
