"WebFeb 25, 2024 · The p-value gives us the probability of observing what we observed, given a hypothesis is true. It does not tell us the probability that the null hypothesis is true. In our example, A p-value of 0.35% will give the probability that we get a sample mean that is more than $183, given the hypothesis that the population mean is $170. " - P value simulation
