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 more than 371 seconds. For a sample of 18 patients, the mean time in which the medicine relieved pain was 379 seconds with a standard deviation of 22 . Assume the population distribution is approximately normal.
Step 1 of 3:
State the null and alternative hypotheses.
Step 2 of 3:
Find the P-value for the hypothesis test. Round your answer to four decimal places.
Step 3 of 3:
Make the decision to reject or fail to reject the null hypothesis.
