WebWe’re given the sample statistics below and need to find the p value. Mean: 330.6 Standard deviation: 154.2 Sample size: 25 Null hypothesis value: 260 Let’s work through the step-by-step process of how to calculate a p-value. First, we need to identify the correct test statistic. WebIn null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct. A very small p-value means that such an extreme observed outcome would be very unlikely under the null hypothesis. Reporting p-values of statistical tests is … pronounce theotokos in greek https://melissaurias.com

WebJul 22, 2024 · Suppose we want to find the p-value associated with a z-score of 1.24 in a two-tailed hypothesis test. To find this two-tailed p-value we simply multiplied the one-tailed p-value by two. The p-value is 0.2149. If we use a significance level of α = 0.05, we would fail to reject the null hypothesis of our hypothesis test because this p-value is ...

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.
