When nicotine is absorbed by the body, cotinine is produced. A measurement of cotinine in the body is therefore a good indicator of how much a person smokes. Listed below are the reported numbers of cigarettes smoked per day and the measured amounts of nicotine (in ng/mL). Is there a linear correlation?

Cigarettes per day (X)	60	10	4	15	10	1	20	7
Cotinine (Y)	179	283	75.6	174	209	9.51	350	43.4

a) Use the critical value method for testing hypothesis. (6pts)

b) What is the regression equation? Is it helpful in this situation? Why or why not?(3pts)

c) Predict the amount of cotinine for 40 cigarettessmoked per day. (1pt)

When people smoke, the nicotine they absorb is converted to cotinine, which can be measured. A sample of 60 smokers has a mean cotinine level of 172.5 ng/ml. Assuming the σ is known to be 99.5 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. 1. Copy and paste the Minitab output for exercise into the document underneath the problem. You are not also required to do these...

When people smoke, nicotine is converted to cotinine, which can be measured. A sample of 40 smokers has a mean cotinine level of 172.5. Assuming that the standard deviation is known to be 119.5, find a confidence interval estimate of 90% of the mean cotinine level for all smokers. What aspect of this problem is not realistic?
