The p value is quizlet
WebbA p-value >0.95 literally means that we have a >95% chance of finding a result less close to expectation and, consequently, a <5% chance of finding a result this close or closer. Often in studies a statistical power of 80% is agreed upon, corresponding with a p-value of approximately 0.01. The ultimate p-value may then be a bit larger or smaller. WebbQuestion: 2.

Thus, X ¯ is significantly greater … WebbObserving a low p-value can be due to one of three reasons [2]: There is a true effect from the tested treatment or intervention. There is no true effect, but we happened to observe a rare outcome. The lower the p-value, the rarer (less likely, less probable) the outcome. The statistical model is invalid (does not reflect reality).

For α = .05, this means 2.5% of the area is in each tail, which, based on the z-table, corresponds to critical values of z ∗ = ±1.96. This is shown in Figure 7.5. 2.
