Answer to Question #107177 in Statistics and Probability for jasmine

Question

LDL - low density lipoprotien - cholesterol is considered the bad cholesterol. A pharmaceutical company conducts a clinical trial on people with high levels of LDL cholesterol. The trial involves a random sample of 11 persons who have high levels of LDL. Each person has their LDL level measured prior to the beginning of the drug trial. Each person is then asked to take a new drug to lower LDL levels. After a period of 4-weeks, the LDL level of each person is measured again. The difference between the initial LDL level and the LDL-level four weeks after taking the drug is then computed.

−0.1,−0.52,−0.33,−1.03,−0.59,−0.97,−0.54,−0.79,−0.37,−0.71,−0.86

Assuming that the difference in the LDL-levels is normally distributed, find a 97% confidence interval for μ, the mean difference in the LDL-level of a person after taking the drug for four weeks.
