Take the following as truth: If the data from a series of tests performed with the same toxicant, toxicant concentrations, and test species, were analyzed with hypothesis tests, precision could only be assessed by a qualitative comparison of the NOEC-LOEC intervals, with the understanding that maximum precision would be attained if all tests yielded the same NOEC-LOEC interval.
Then the following statement: "They needed various data to test for toxicants." is true, false, or inconclusive?
Answer: True
