The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.01 level that the drug stays in the system for more than 398 minutes. For a sample of 67 patients, the mean time the drug stayed in the system was 402 minutes. Assume the variance is known to be 529. Enter the decision rule to reject or accept null hypothesis and show all work
