A new drug to treat a certain condition is being tested. The null hypothesis of the test is that the drug is not effective. For the researchers, the more consequential error would be for the drug to be effective, but the test does not detect the effect. Which of the following should the researchers do to avoid the more consequential error?     Increase the significance level to increase the probability of Type II error. A Increase the significance level to decrease the probability of Type II error. B Decrease the significance level to increase the probability of Type II error. C Decrease the significance level to decrease the probability of Type II error. D Decrease the significance level to decrease the standard error.
