Where, p ^ = Sample Proportion. P0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z value obtained.
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 ...
