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 321 minutes. After performing a hypothesis test, she decides to reject the null hypothesis.
What is the conclusion?
There is sufficient evidence at the
0.02 level of significance that the drug stays in the system
for more than
321 minutes.
There is not sufficient evidence at the
0.02 level of significance that the drug stays in the
system for more than
321 minutes.

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 307307 minutes. For a
sample of 6767 patients, the mean time the drug stayed in the
system was 315315 minutes. Assume the population standard deviation
is 2323.
Step 5 of 6:
Identify the level of significance for the hypothesis test.
