We determine if we have evidence against the null hypothesis, in favor of the alternative hypothesis, based on how the P-value compares to our chosen significance (or alpha) level. Remember that if the P-value is less than or equal to the significance level, we say that we have evidence against the null hypothesis. If the P-value is larger than the significance level, we do not have enough evidence against the null hypothesis (i.e., we cannot rule out the null hypothesis as a reasonable explanation for the observed sample outcome). If we assume here, with this example, that we are using a significance level of 0.05, what should we conclude?
