The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.1 level that the medicine relieves pain in less than 372 seconds. For a sample of 41 patients, the mean time in which the medicine relieved pain was 369 seconds. Assume the standard deviation is known to be 23. State the null and alternative hypotheses for the above scenario.
