Checking that assumptions have been met is the first step in conducting the single-sample t test. This is because the t test is a parametric test, and parametric tests require that certain assumptions be met in order to be valid. These assumptions include:* The sample is randomly selected from the population.* The population is normally distributed.* The variance of the population is known.If any of these assumptions are not met, then the t test may not be valid, and the results may be misleading.
