Consider the test of the hypotheses:
Null: (sigma1)^2>=(sigma2)^2
Alternative: (sigma1)^2<(sigma2)^2
where α = 0.05 and:
n1 = 8 and s1 = 13.0
n2 = 10 and s2 = 11.5.
What is the test statistic for F?
Your Answer:
1.278
Correct Answer:
1.278
If the alternative hypothesis for two variances has "<", couldn't you switch the s1 and s2 in the f-stat equation to create an upper-tail test? if so, my test statistic would be 0.783
