The p-value is the probability that the event occurs, assuming that H 0 is true; that is, the coin is fair (if we were in the universe where H 1 is true, then the p-value would be 1 for all the events). The occurrence of a tail once is quite regular, and for a fair coin, the probability of occurrence of Event 1 is 0.5.

WebThis is the probability that our t value x will be > 1.5. In general, when we sample a value x at random from a t distribution with d degrees of freedom, the probability that x > q is given by: P ( x > q) = 1 − C D F d ( q) where C D F d is the cumulative distribution function for a t value with d degrees of freedom. WebThis is an exact, two-sided test of the null hypothesis that the probability of success in a Bernoulli experiment is p.
