uestion Completion Status: QUESTION 1 An ANOVA involves samples from seven populations with a total of 43 observations. The numerator and denominator degrees of freedom for the F test would be 036 and 6. O 42 and 5 06and 36. O 7 and 43. QUESTION 2 Consider the partial ANOVA table shown below.

Explanation / Answer

1) for degree of freedom between groups =k-1= 7-1 =6

and with in groups =n-k =43-7=36

option 6 and 36 is correct

2)

MSE =(380-180)/(19-3)=12.5

3)

critical F at 4,27 degree of freedom and 0.01 level =4.11

4)

null hypothesis:mu1 =mu2=mu3

5)sampled populations have equal variances.
