F test to compare two variances
data: x and y
F = 0.8795, num df = 99, denom df = 99, p-value = 0.5242
alternative hypothesis: true ratio of variances is not equal to 1
95 percent confidence interval:
0.5917706 1.3071567
sample estimates:
ratio of variances
0.8795095
Since the p-value = 0.5242, which is much higher than 0.05, the hypothesis that the variances of x and y are
