Assignment 7: Problem 10 (1 point) 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 = 15 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. -1.11, -0.25, -0.06, -0.88, 0.06, -0.81, -0.41, -0.68, -0.16, -0.43, -0.49,-0.57, -0.58, -0.37, -0.68 Data from the sample, are saved in the Download .csv file. Assuming the difference in the LDL-levels is Normally distributed, find a 99% confidence interval for , 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. SH
