A new drug is proposed to lower total cholesterol and a study is designed to evaluate the efficacy of the drug in lowering cholesterol. Fifteen patients agree to participate in the study and each is asked to take the new drug for 6 weeks. However, before starting the treatment, each patient's total cholesterol level is measured. The initial measurement is a pre-treatment or baseline value. After taking the drug for 6 weeks, each patient's total cholesterol level is measured again and the data are shown below.. Initial Cholesterol Cholesterol at Week 6 215 205 190 156 230 190 220 180 214 201 240 227 210 197 193 173 210 204 230 217 180 142 260 262 210 297 190 184 200 193 Based on the scenario above, analyse the data with appropriate statistical methods and describe your findings in details (both descriptive and inferential). Use alpha=0.05 [Hint: while describing inferential use hypothesis, test statistics confidence interval etc.]
