A pharmaceutical company needs to know if its new cholesterol
drug, Praxor, is effective at lowering cholesterol levels. It
believes that people who take Praxor will average a greater
decrease in cholesterol level than people taking a placebo. After
the experiment is complete, the researchers find that the 47 47
participants in the treatment group lowered their cholesterol
levels by a mean of 23.6 23.6 points with a standard deviation of
4.3 4.3 points. The 33 33 participants in the control group lowered
their cholesterol levels by a mean of 21.7 21.7 points with a
standard deviation of 4.6 4.6 points. Assume that the population
variances are not equal and test the company’s claim at the 0.10
0.10 level. Let the treatment group be Population 1 and let the
control group be Population 2.
Step 2 of 3 : Compute the value of the test statistic. Round
your answer to three decimal places.
