Question
![Suppose you are a researcher in a hospital. You are experimenting
with a new tranquilizer. You collect data from a random sample of
10 patients. The period of effectiveness of the tranquilizer for
each patient (in hours) is as follows:
Hours
2.2
2.4
2.5
2.4
2.6
2.3
2.5

a) What is a point estimate for the population mean length of
time. (Round answer to 4 decimal places)
b) What must be true in order to construct a confidence interval in
this situation?
Select an answer
c) Construct a 99% confidence interval for the population mean
length of time.. Enter your answer as an open-interval (i.e.,
parentheses example (5.2314,8.1245)) Round upper and lower
bounds to 4 decimal places.
d) What does it mean to be "99% confident" in this problem?
O There is a 99% chance that the confidence interval contains
the sample mean time.
O The confidence interval contains 99% of all sample times.
99% of all times will fall within this interval.
99% of all confidence intervals found using this same sampling
technique will contain the population mean time.
e) Suppose that the company releases a statement that the mean
time for all patients is 2 hours.
Is this possible? ?
Is it likely?
