In the last seconds of the video, Sal briefly mentions a p-value of 5% (0.05), which would have a critical of value of z = (+/-) 1.96. Since the experiment produced a z-score of 3, which is more extreme than 1.96, we reject the null hypothesis. WebThe formula for the calculation for P-value is. Step 1: Find out the test static Z is. z = p ^ − p 0 p o ( 1 − p 0) n. 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. mayfield school campus midlothian
