Rejecting h0
WebP Values. The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested. P is also described in terms of rejecting H0 when it is actually true, however, it is ... WebThe _ hypothesis states that a parameter is equal to a certain value while the _ hypothesis states that the parameter differs from this value

Web6.5 - Power. The probability of rejecting the null hypothesis, given that the null hypothesis is false, is known as power. In other words, power is the probability of correctly rejecting H 0. A one sample t-testis used to test whether or not the mean of a population is equal to some value.
