One-way analysis of variance is being used to test the equality of two population means using a sample of size 10 from the first population and a sample of size 12 from the second population.The test statistic (F_stat) turns out to be 5.160.If an equivalent t test had been used to test the "no difference in population means" null hypothesis, what would be the test statistic (t_stat) for the t test? A)5.160 B)10.320 C)2.272 D)2.580

The test statistic for the t-test can be found by taking the square root of the F-test statistic because the F-distribution is the square of the t-distribution. Therefore, the t-test statistic is the square root of 5.160, which is approximately 2.272.
