When people smoke, the nicotine they absorb is converted to cotinine, which can be measured through blood tests. A random sample of 40 smokers has a mean cotinine level of 172.5 ng/ml. Assuming that = 119.5 ng.ml, test the claim that the mean cotinine level of all smokers is equal to 200.0 ng/ml. Use a 0.05 significance level.
