Specifically, when we conduct a hypothesis test, we must choose a significance level at the outset. Common choices for significance levels are 0.01, 0.05, and 0.10. If the p-values is less than our significance level, then we can reject the null hypothesis. WebThe P-value is the smallest significance level α that leads us to reject the null hypothesis. Alternatively (and the way I prefer to think of P -values), the P-value is the probability that we'd observe a more extreme statistic than we did if the null hypothesis were true. in which direction is fine gold creek flowing
