I think the test statistic F is the ratio of the variances: F=σ12/σ22= (3.7/3.1)2=1.4246. (Standard deviation is the square root of variance)
H0: F=1, H1: F≠1 at the specified confidence level of 95% (α=0.05).
The sample sizes are the same so the DOF (degrees of freedom)=9-1=8.
Since s1>s2 we need the right-tailed F-distribution FCDF0.05 to find the critical value at 8 DOF for both samples. I get 3.44 from tables for the right tail of the distribution. 1.4246 is less than the critical value so we don't have sufficient evidence to conclude that the different standard deviations are significantly different, because we cannot reject H0.
