The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.01 level that the drug stays in the system for less than 300 minutes. For a sample of 14 patients, the mean time the drug stayed in the system was 297297 minutes with a standard deviation of 22. Assume the population distribution is approximately normal.
Step 1 of 5:
State the null and alternative hypotheses
Step 2. Find the value of the t test statistic. ( Round your answer to 3 decimal places.)
Step 3. Specify if the test is one-tails or two-tailed A) One-Tailed Test B) Two-Tailed Test
Step 4. Determine the decision rule. (Round your answer to 3 decimal places.) Reject H0 if t<
Step 5. Determine the conclusion. A) Reject Null Hypothesis B) Fail to Reject Null Hypothesis

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...

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.
