Webbvalued), associated with either a known probability density function (continuous distribution) or a known probability mass function (discrete distribution), denoted as fθ, we may draw a sample x1, x2, ..., xn of n values from this distribution and then using fθ we may compute the probability density associated with our observed data: WebbType I Error: Definition Probability Statistics Example Alpha False Positive StudySmarter Original. ...

WebbIt is true that with a standard hypothesis test you either reject the null hypothesis or you do not. I.e. type II error + power = 1 under H A and non-rejection probability + type I error = 1 under H 0. However, the statement the way you phrase it is not true.
