The test statistic is calculated by dividing the difference between the sample mean and the hypothesized mean by the standard error of the mean. In this case, the sample mean is 52.1, the hypothesized mean is 46.9, and the standard error of the mean is 10.0. Therefore, the test statistic is (52.1 - 46.9) / 10.0 = 5.21.
