- Determine if the following statement is true or false. If you believe that the statement is false, briefly explain why you think it is false. Small values of x² imply that the null hypothesis in a chi-squared test is true. Choose the correct answer below. A. The statement is true. B. The statement is false because hypothesis tests do not prove the truth of the null hypothesis. C. The statement is false because the value of x² is not considered when determining whether the null hypothesis is true. D. The statement is false because large values of x² imply that the null hypothesis is true.The null and alternative hypotheses are given.
