A new drug is introduced that is supposed to reduce fevers. Tests are done with the drug. The drug is
given to 40 people who have fevers. It is found that the mean time that it takes for the fever to get back
to normal for this test group is 320 minutes with a standard deviation of 60 minutes. Find the 90%
confidence interval for the mean time that the drug will take to reduce all fevers for all people.

C.




D.




E.



2. List the values you would insert into that equation.



3. State the final answer to the problem

Your Answer:

2. n+40, =320, and s=60, z=1.645(90%confidencelevel)

3. The final asnwer to the problem is:

We will use these values in the equation:
