I need help with this question. How would I determine the test statistic and test for the decision at 99.9% confidence?

in these data and using the dependent sample analysis approach, test the claim at 95% onfidence that the urine cotinine concentrations in the truck cab were higher than those at home. a) State the Null and Alternative Hypotheses (1) b) Prepare the PDF and state the Decision Rule (1,1) C) Determine the test statistic (2) d) State your decision (1) e) State the interpretation. (1) f) Is your decision the same at 99.9% confidence? Explain. (1,2)gestion #4. (10 marks)_Lecture Week 6, Lecture 1 There have been many studies trying to link the association between different biomarkers and environmental measures of second hand smoke (SHS). Cotinine is the gold standard biomarker for airborne nicotine and in particular for SHS exposure assessment in children with asthma (Household Smoking Behavior: Effects on Indoor Air Quality and Health of Urban Children with Asthma, Buty, Breysse, et. Al, Matern Child Heath J (2011) 15:460-468) The bad thing about urine cotinine levels is that it is persistent and stays in the body for extended periods of time. So trying to relate urine cotinine to the number of cigarettes smoked in a home is really quite a hard thing to do because of this latent feature. 100 Urine Cotirins (ng/ml) A new study was designed to measure the 30 urine cotinine levels of long-distant haulers (truckers) who smoked. The study was trying 10 to get an understanding of SHS in a confined area (the cab of the big rig) and an open area of the home Nine truckers were recruited for the study and the results were as follows. The 20 40 condition being that the truckers had to be Number of cigarettes smoked by all smokers driving for a period of at least 8 hours and then their urine was immediately sampled versus the same trucker at home for at least one day before their urine was sampled. The truckers were not to deviate from their smoking habits. In other words, if they smoke six cigarettes every 8 hours in the truck, then they smoked six cigarettes every 8 hours at home.
