Indicate which single answer (either A, B, or C,) best completes the question.

What statement about hypothesis testing is TRUE?

a) The reference value in the hypothesis statements comes from the sample data.

b) The test statistic (e.g., z-value) indicates how many "units of spread" (i.e., standard deviation of sampling distribution) there are between the sample statistic and the reference value.

c) Large p-values indicate support for the alternative hypothesis.

I think the answer is b but not sure...
