WebTo reject the null hypothesis, the p-value must be less than alpha. In our example, if we obtain a sample mean of 550, the p-value is the probability of observing a mean as large or larger than 550 if the population mean really is only 500. The p-value is not the probability that the null hypothesis is true. In fact, the probability that the ... WebNov 3, 2011 · Origin of the 5% p-value threshold.

Conclusions: In randomized controlled trials, main endpoint p-values larger than p=0.95 will be rare, because they would indicate similarities closer than compatible with a normal distribution … WebP values indicate how incompatible the observed data may be with a null hypothesis; “P<0.05” implies that a treatment effect or exposure association larger than that observed would occur... little big photography
