What is the critical F value when the sample size for the
numerator is sixteen and the sample size for the denominator is
ten? Use a two-tailed test and the 0.02 significance level. (Round
your answer to 2 decimal places.)
What is the conservative critical F statistic if your sample
size is 50 and you are comparing 3 groups of participants (at the

QUESTION 2
Let x be a random variable representing the SAT math
score of student. We may assume that x has a normal
distribution and that the population standard deviation is 25. A
large university claims the average SAT math score for incoming
freshman is 650. You...
Using your F Table, what is the critical value for a set of
sample data that has a df between of 3 and a df within of 10, using
a significance level of 0.05?
What is the critical value of F? Show df.k=6 n=6 (between-subjects design)
What is the critical value of F? Show df.k=3 n=10 (between-subjects design)
What is the critical value of F? Show df.
k=6 N=6 (within-subjects design)
What is the critical value of F? Show df.
k=3 N=10 (within-subjects design)
What is the critical value of F? Show df.
k=4 N=8 (within-subjects design)
You have 4 groups with an overall sample size of n = 20. The F
