WebOct 31, 2024 · A single t-test generates a single t-value. So, to get distribution, we need to take multiple random samples of equal size from the same population and feed them through the same t-test. This way we will get a spread of t-values, which can be plotted as a sampling distribution – a special case of probability distributions. WebRory wants to use these sample data to conduct a t test on the mean. Assume that all conditions for inference have been met. Calculate the test statistic for Rory's test.
