The test statistic for testing H0: μ = 100 against HA: μ ≠ 100 was t = 3.3, with P-value 0.001.  Then, Choose the best asnwer below: A. there is not strong evidence that μ = 100. B. there is not strong evidence that μ < 100. C. this must be wrong, because a large t test statistic must have a large P-value. D. there is strong evidence that μ > 100. E. there is not enough information here to draw a conclusion.
