To avoid the problem of not having access to tables of the f distribution when a one-tailed test is required and with f values given for the lower tail, let the

a. smaller sample variance be the numerator of the test statistic.
b. larger sample variance be the numerator of the test statistic.
c. sample variance from the population with the smaller hypothesized variance be the numerator of the test statistic.
d. sample variance from the population with the larger hypothesized variance be the numerator of the test statistic.
