As a GP you want to evaluate the possibility that the values for cholesterol in the town you practice medicine, due to genetics and the remoteness of the rural area, might be substantially different from those reported for the population at large which are found to be 152 mg/dL. So you design a preliminary study in which you randomly recruit 100 healthy volunteers amongst the inhabitants of that town and proceed to determine their levels of cholesterol to compare them with the levels of 100 randomly selected individuals whose residence is not that town. Which test would you use to analyse the results? a. The Sign test b. A dependent sample t-best c. A one sample I-test d. The Wilcoxon test e. An independent sample I-lost
