Scientist Irish used a paired t-test to test the effectiveness of a drug she is developing. She obtained a p-value = 0.005 (she used α = 0.05). Suppose the drug actually works. Which of the following statements is correct? Irish should not have rejected the null hypothesis because the p-value is too large. Type I error occurred. Type II error occurred. There was no error.
