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
