P value u4n
WebSo, we have to look at -2.0 in the z column and the value in the 0.09 column. Since the normal distribution is symmetrical, the area to the right of the curve is equal to that on the left. So, we get the P-Value as 0.0183. P Value = 0.0183. Since the P-Value is less than the significant level of 0.05 (5%), we reject the null hypothesis. Example #3 WebThe formula for a one-tailed binomial test is: p-value = P (X ≥ k), where X is the number of successes, k is the number of observed successes (51), and P is the probability of success (0.5). Using this formula, the p-value was calculated to be 0.049, which is less than the significance level of 0.05. Therefore, we can reject the null ...
