Actual test output:

>var-test (c1, c1mm)

F-test to compare two variances

data: c1 and c1mm

F = 1.0017, num df = 462, denom df = 462, p-value = 0.9857

Alternative hypothesis: true ratio of variances is not equal to 1

95percent confidence interval: 0.834491 1.202329

Sample estimates: ratio of variances 1.001665
