Which statement best describes the goal of hypothesis testing?

Explanation:
In hypothesis testing, the aim is to determine whether the data provide evidence against a baseline assumption called the null hypothesis. You model what would happen if the null were true and ask how likely it is to observe the data you actually got. If that likelihood is very small compared with your chosen threshold, you conclude that the results are unlikely to have occurred by chance and you reject the null. This is why the statement that best describes the goal is that the results are unlikely to have occurred by chance. Remember, results being unlikely under the null does not guarantee truth—sampling variability means outcomes can mislead you. Larger sample sizes generally give more precise evidence and can affect whether results appear significant, and results that are significant in one context don’t automatically apply to every possible scenario.
