The t-test is used when the standard deviation is unknown and the sample size is small, and it is a type of hypothesis test that uses the t distribution. Therefore, A is the best choice. The F-test is used to compare variances between two groups, and the p-test is not a commonly used statistical test. The z-test is used when the standard deviation is known and the sample size is large, so it is not appropriate for this scenario. The k-means test is a clustering algorithm and not a hypothesis test.
