The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.05 level that the drug stays in the system for more than 366 minutes. For a sample of 47patients, the mean time the drug stayed in the system was 371 minutes. Assume the population standard deviation is 25. Make the decision to reject or fail to reject the null hypothesis.
