Final answer:
The data support or refute the null hypothesis.
Step-by-step explanation:
In statistics, the null hypothesis is a statement that there is no significant difference, effect, or relationship. It is a fundamental concept in hypothesis testing, a statistical method used to make inferences about a population based on a sample of data
In hypothesis testing, the data either support or refute the null hypothesis based on whether the actual observations match the expected observations. If the actual observations differ from the expected observations, the null hypothesis is refuted. Therefore, the correct answer is B) The null hypothesis is refuted.
