... P-value (p. 487) – the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true. Put another way, the P-value is the likelihood or probability that a sample will result in a statistic such as t ...

... the probability that the test fails to reject H0 as a function of θ, where θ is the est parameter. • OC(θ) = P{test fails to reject H0 | θ} • For θ values included in H1 the OC function is the β –risk. The power function is: π(θ) = P{Test rejects H0 | θ} = 1 – OC(θ) • Example: In SAT coaching, for t ...
