Webb, the p-value = 0.03, then the probability of randomly selecting a sample of 100 users who spend, on average, 25 minutes on the yellow-background website is only 3%! In other words, the likelihood of getting a sample mean of 25 given that all sample means should be near 20 is only 3%.

Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859.

WebbIf the null hypothesis is true, a p-value of 0.01 indicates that there is a 1% probability of detecting the findings or more severe outcomes. Hence, there is a 99% confidence level that the findings are statistically significant and a 1 in 100 probability that the results were acquired only by chance (i.e., not due to chance). WebbThe most common errors are mistaking a low p-value with evidence for lack of effect or difference, mistaking statistical significance with practical significance, as well as treating the p-value as a probability, related to a …

Webb10 aug. 2024 · The p -value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
