Problem 10. (1 point) LDL - low density lipoproteinolesterol 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. -0.68, -0.4, -0.83, -0.66, -0.1, -1.08, 0.24, -0.43,-0.17,-0.71,-0.3 Data from the sample, are saved in the Download .csy file. Assuming the difference in the LDL-levels is Normally dis- tributed, find a 90% 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
