Webb31 maj 2024 · Every one of these samples has a mean, and if we collect all of these means together, we can create a probability distribution that describes the distribution of these means. This distribution is always normal (as long as we have enough samples, more on this later), and this normal distribution is called the sampling distribution of the sample … Webb6 jan. 2016 · We found that the probability that the sample mean is greater than 22 is P ( > 22) = 0.0548. Suppose that is unknown and we need to use s to estimate it. We find that s = 4. Then we calculate t, which follows a t-distribution with df = (n-1) = 24. From the tables we see that the two-tailed probability is between 0.01 and 0.05.
