A pharmaceutical company introduced a new drug that would reduce
cholesterol levels. A researcher selected 10 cholesterol patients
and tested them for their cholesterol level. The subjects were then
placed on the new drug for a period of 6 months, and the
cholesterol level reading was taken again. Both the results are
given below. Assume the samples are random and dependent, and the
populations are normally distributed. Use 0.01 level of
significance and test whether there is evidence of reduced...

A new drug to treat high cholesterol is being tested by
pharmaceutical company. The cholesterol levels for 18 patients were
recorded before administering the drug and after. The average
difference in cholesterol levels (after - before) was 4.19 mg/dL
with a standard deviation of 8.055 mg/dL. Using this information,
the calculated 90% confidence paired-t interval is (0.887, 7.493).
Which of the following is the best interpretation of this
interval?
