- A clinical lab wants to evaluate the resistance power of itsnew medicine. It has provided the new medicine to a random sampleof 300 rats and retained the old drug for the remaining (200 rats).Three months after the dosage of the new drug, the group with thenew medicine has a resistance of 40.2 with a s.d of 6.5 while thegroup with the old drug had an average of 35 with a s.d of4.5.
NOTE: Follow all the steps inhypothesis testing. You can use Graphpad for this one.
- What is your Null and Alternate Hypothesis. (0.5 point)
- Did the new medicine result in significantly higher resistanceof the dogs? State the value of the test-statistic, the p-value andthe 95% confidence interval. (1 point)
(c)What do you mean by saying thatthis is the confidence interval in this case? (0.5 point)
