Need help with these questions: I have already answered 27 out of the 30 accept these last three:
8. Given the significance level 0.01, the Fvalue for the degrees of freedom, d.f. = (7,3) is.
A) 8.45
B) 27.67
C) 5.89
D) 14.62
9. Oneway ANOVA is performed on three independent samples with: n1 = 6, n2 = 7 , and n3 = 8. The critical value obtained from the Ftable for this test at the 2.5% level of significance equals:
A) 3.55
B) 39.45
C) 4.56
D) 29.45
10. A randomized block design ANOVA has five treatments and four blocks. The computed test statistic (value of F) is 4.35. With a 0.05 significance level, the appropriate table value and conclusion will be:
A) 14.37: accept the null hypothesis
B) 3.11: accept the null hypothesis
C) 3.26: accept the null hypothesis
D) 3.26: reject the null hypothesis

All of these questions require you to read the Fdistribution table for the values stated. I'll give you a few hints and see if you can take it from there.
For #8:
It's either A or B. Read the table using the degrees of freedom and significance level as guidelines.
For #9:
Degrees of freedom is 2, 18 (for a oneway Anova). Check the table.
For #10:
If the test statistic exceeds the critical value, reject the null. If the test statistic does not exceed the critical value, then do not reject the null.
I hope this will help get you started.
