WebFeb 13, 2024 · To determine the p-value, you need to know the distribution of your test statistic under the assumption that the null hypothesis is true.Then, with the help of the cumulative distribution function (cdf) of this distribution, we can express the probability of the test statistics being at least as extreme as its value x for the sample:Left-tailed test: p … WebNote that it does not mean that the estimate has a 90% chance of occurring – that is a very different concept. P50 is more likely to occur because it is closer to the mean. For this sample of observations, our P50 would be 95 which is exactly the mean (i.e. 95). There is a reason for this which is explained later in this article.
