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 n = 16 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 to take a new drug that is believed to lower ones 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. -0.56, -0.07,-0.2, -0.42, -0.32, -0.99, -0.26, -0.32, -0.73, -0.51, -0.59, -0.62, -0.78, -0.04, -0.5, 0.13 Data from the sample, are saved in the Download.csv file. Assuming 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. Use at least four decimals for your lower and upper bounds. To avoid Rounding errors you use use R- Studio and not Tables. ☐ SHS☐
