The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.02 level that the drug stays in the system for more than 379 minutes. After performing a hypothesis test, she decides to reject the null hypothesis. What is the conclusion?
The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.050.05 level that the drug stays in the system for more than 377377 minutes. For a sample of 1818 patients, the average time the drug stayed in the system was 381381 minutes with a standard deviation of 2121. Assume the population distribution is approximately normal. What is the null hypothesis Find the P-value for the hypothesis test. Round your...

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 357 minutes. For a sample of 62 patients, the mean time the drug stayed in the system was 365 minutes. Assume the population variance is known to be 441. Step 1 of 3: State the null and alternative hypotheses. Step 2 of 3: Find the P-value for...
The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.02 level that the medicine relieves pain in more than 390 seconds. After performing a hypothesis test, she decides to reject the null hypothesis. What is the conclusion? Answer Tables Keypad There is sufficient evidence at the 0.02 level of significance that the medicine relieves pain in more than 390 seconds. There is not sufficient evidence at the 0.02...
