A.  8.57, 11.66

B. 11/66, 30.00

Answer 1

4) An ANOVA model with 4 groups and 10 subjects in each group has a total SS equal to 400, and within SS equal to 300, The MS between and the F value are equal to?

k = 4 , N = 40

Using excel

* Correct Answer : 33.33 , 4.00

5) For an ANOVA model with 3 groups and total of 27 subjects, the critical value for rejecting the null hypothesis at the 0.05 level of significance is.

A. 99.50

B.  3.40

Answer : k = 3 , N = 27

DF Numerator = 3 - 1 = 2

DF Denominator = 27 - 3 = 24

Using Excel , at alpha = 0.05

Critical value = =FINV(0.05,2,24) = 3.40

• B. 3.40
