Final answer:
A p-value of 0.04 means there is a 4% chance of observing the data if the null hypothesis is true. The results are statistically significant and reject the null hypothesis.
Step-by-step explanation:
The p-value represents the probability of obtaining results as extreme as or more extreme than the observed results, assuming that the null hypothesis is true. In this case, a p-value of 0.04 means that there is a 4% chance of observing the data if the null hypothesis is true.
Since the p-value is less than the typical significance level of 0.05, we can conclude that the results are statistically significant and reject the null hypothesis in favor of the alternative hypothesis.
