The formula for calculating the F statistic for two independent random samples that each follow a normal distribution and have equal variances is F = (sample variance of the first sample) / (sample variance of the second sample). Therefore, option B is the correct formula for calculating the F statistic. Options A and D have incorrect characters and do not represent a valid formula. Option C shows the formula for calculating the Z statistic, which is used when the population standard deviation is known, but this is not the case in this scenario.
