How do you find a p value

WebIf the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a. If the p p -value is greater than or equal to the significance level, then we fail to reject the null hypothesis H_0 H 0, but this doesn't mean we accept H_0 H 0.
