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 less than 386 minutes. For a sample of 47 patients, the mean time the drug stayed in the system was 382 minutes. Assume the population standard deviation is 24. Please label everything, as it can be hard to read at times. P value=, level of significance is, etc Step 4 of 6 : Find the P-value of the test statistic. Round your answer to four decimal places. Step 5 of 6: Identify the level of significance for the hypothesis. Numerically, 6 decimal places Step 6 of 6: State if we reject null hypothesis or not
