The test statistic for a one-sample t-test is calculated as the difference between the sample mean and the hypothesized population mean, divided by the standard error of the mean. In this case, the sample mean is 10, the hypothesized population mean is 12, and the standard error of the mean is 2. Therefore, the test statistic is (10 - 12) / 2 = -1.
