In testing the difference between population variances of two normally distributed populations using independent random samples,it is a common practice to compute the F statistic to assess if the value is greater than or equal to one.

This is true. The F statistic is calculated as the ratio of the sample variances, and is used to test the null hypothesis of equal variances in two populations. An F statistic greater than or equal to 1 suggests that the variance of one population is larger than the other, while an F statistic less than 1 suggests that the variances are similar. The F distribution is used to determine the probability of obtaining a particular F statistic, given the sample sizes and variances.
