When testing for the equality of 3 population means, we should use the F-test statistic. Option A is the F-test statistic. The t-test statistic is used for testing the equality of means when the sample size is small (less than 30) or when the population standard deviation is unknown. The z-test statistic is used when the population standard deviation is known. Option D is not a valid test statistic.
