Among all the options given the assumption that f test for equality of variances assumes that the population is normally distributed.
Given that f test for equality of variances has been taken.
We are required to give answer to the question that what f test for equality of variances assumes.
F test is basically any statistical test in which the test statistic has an F distribution under the null hypothesis. It is often used when comparing statistical models that have been fitted to a data set,in order to identify the model that fits the population from which the data were sampled.
F  test for equality of variances assumes that the population is normally distributed.
Normal distribution is basically a distribution that is symmetric about the mean,showing that data near the mean are more frequent in occurrence than data far from the mean.
Hence among all the options given the assumption that f test for equality of variances assumes that the population is normally distributed.
