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=14 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.−0.72,−0.78,−0.27,−0.28,−0.81,−0.61,−0.51,−0.4,−0.92,−0.55,−0.35,−0.61,−0.15,−0.55 Data from the sample, are saved in the picture. Assuming the difference in the LDL-levels is Normally distributed, find a 91% 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 Table
